## What is the angle of a 6 sided shape?

A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

## Can a Pentagon have 2 right angles?

An equilateral (but not equiangular) pentagon may contain no more than two right angles; if it has two right angles, then the remaining angles are 120°, 60°, and 120°, and its shape resembles a simple house.

## What type of angle is a triangle?

In an acute triangle, all the angles of a triangle are less than 90 degrees. In an obtuse triangle, one of the angles of a triangle is greater than 90 degrees. In a right triangle, one angle measures 90 degrees and the other two angles are acute.

## How many right angles are in Triangle?

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees…

## Can Triangle have 2 right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. Thus, it is not possible to have a triangle with 2 right angles.

## Do all right triangles equal 180?

Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).
