(A “regular” polygon has all equal sides and all equal angles.) An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles.
Equilateral triangle. The Equilateral triangle shown on the left has three equal sides and three equal angles.
Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.
Scalene Triangle. The Scalene Triangle has no congruent sides.
Acute Triangle.
Obtuse Triangle.
Equilateral triangle. The Equilateral triangle shown on the left has three equal sides and three equal angles.
Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.
Scalene Triangle. The Scalene Triangle has no congruent sides.
Acute Triangle.
Obtuse Triangle.

In this manner, which triangle is scalene?

Scalene Triangle. A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. SEE ALSO: Acute Triangle, Equilateral Triangle, Isosceles Triangle, Obtuse Triangle, Triangle.

What is the definition of acute scalene triangle?

An ACUTE triangle contains three acute angles. (In other words, each angle of an acute triangle is less than 90 degrees.) A SCALENE triangle is one in which all sides have different lengths (and therefore, all angles have different measures).

What are the 4 types of triangles?

## What is the definition of acute scalene triangle?

An ACUTE triangle contains three acute angles. (In other words, each angle of an acute triangle is less than 90 degrees.) A SCALENE triangle is one in which all sides have different lengths (and therefore, all angles have different measures).

## What is an obtuse right triangle?

An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180°, no triangle can have more than one obtuse angle.

## How do you draw an isosceles triangle?

Step 1: Draw a straight line QR 6 cm long. Step 2: Using a protractor draw an angle of 50° from Point Q. Step 3: Using a protractor draw an angle of 50° from Point R. The angles opposite the equal sides in an isosceles triangle are equal.

## Is it possible to have an obtuse equilateral triangle?

You are right – an equilateral triangle cannot have an obtuse angle. In fact, the angles are all “fixed” – they are each 60 degrees. Try this: take three equal length pencils and form a triangle. Now take three more pencils and try to form a triangle that has angles different from the first.

## How can you use the perpendicular bisector of a segment to draw an isosceles triangle?

If you construct the perpendicular bisector of the line segment AB, every point on the perpendicular bisector will be the same distance from both point A and point B. To construct your isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B.

## Is it possible to have a right equilateral triangle?

In an equilateral triangle, all the sides are equal. If we use the longest side theorem which say in the triangle the longest side is across the largest angle. Since all the sides are equal then the angles must be equal too. So we can’t have an Right angled equilateral triangle.

## What is an equilateral quadrilateral?

An equiangular quadrilateral, i.e. the one with all angles equal is a rectangle. All angles of a rectangle equal 90°. An equilateral quadrilateral, i.e. the one with all sides equal, is a rhombus. In a square, rectangle, or rhombus, the opposite side lines are parallel.

## What is an equilateral triangle?

Here’s an example of an equilateral triangle: You’ll notice that along with this triangle’s sides, its three angles are also all equal. Since the sum of a triangle’s angles is always 180 degrees, each angle in an equilateral triangle must measure 60 degrees.

## How do you construct a square with a compass?

Construct: a square inscribed in a circle.
STEPS:
Using your compass, draw a circle and label the center O.
Using your straightedge, draw a diameter of the circle, labeling the endpoints A and B.
Construct the perpendicular bisector of the diameter, .
Label the points where the bisector intersects the circle as C and D.

## How do you construct a hexagon?

Method 2 Drawing a Rough Hexagon Using a Round Object and a Ruler
Trace the round rim of a glass with a pencil.
Draw a horizontal line through the center of your circle.
Draw an X over the halved circle, splitting it up into 6 equal sections.
Turn each of the six sections into triangles.
Erase your guiding lines.

## How do you make a parallelogram?

Method 2 Constructing a Parallelogram with a Compass
Start with an L shape. Draw two straight lines that share a corner.
Get a compass.
Understand the equal sides method.
Set your compass to the length of the bottom side.
Copy this length.
Copy the length of the left side.
Find the top right corner.
Draw the top side.

## What is an isosceles right triangle?

A right triangle with the two legs (and their corresponding angles) equal. An isosceles right triangle therefore has angles of , , and . For an isosceles right triangle with side lengths , the hypotenuse has length , and the area is . The hypotenuse length for is called Pythagoras’s constant.

## Can you have a triangle with two right angles?

That would contradict with the fact that, sum of all angles of a triangle is 180. No, you can not have a triangle with 2 right angles. The sum of the internal angles of a triangle is 180 degrees. Two right angles together make 180 degrees Your third angle will be 0 degrees which is absurd.

## Can an isosceles triangle be obtuse?

An isosceles triangle is a triangle that has at least two equal sides. The triangle below on the left is not an obtuse isosceles triangle, but the one on the right is indeed an obtuse isosceles triangle as the top center angle is certainly more than 90 degrees but less than 180 degrees.

## What is the definition of scalene triangle?

Scalene Triangle. A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. SEE ALSO: Acute Triangle, Equilateral Triangle, Isosceles Triangle, Obtuse Triangle, Triangle. CITE THIS AS: Weisstein, Eric W. “

## Can a right triangle have more than one obtuse angle?

Triangle cannot have more than one obtuse angle because there are 3 side and if you add three sides it equals to 180 degree and obtuse angle is greater than 90 degree and the other two has to be less than 90 degree. By definition, the sum of angles of a triangle is 180 degrees.

## How do you make an equilateral triangle?

Method 1 Using a Compass
Draw a straight line. Lay your ruler on the paper, then trace a pencil along the straight edge.
Span the segment with your compass.
Trace a quarter-circle arc.
Switch the compass around.
Draw a second arc.
Mark the point where the two arcs cross.
Finish the triangle.

## What is an obtuse scalene triangle?

In an obtuse triangle, one angle is greater than a right angle—it is more than 90 degrees. An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right angles—each one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene. Common Formulas.
