What is a pentagon with 2 right angles?

If you take a rectangle or a square and replace one of the sides with two sides that come together to a point, you will have an irregular pentagon that has two right angles. Cutting off one corner of a rectangle or square to create a fifth side creates a pentagon with three right angles.

What are the angles in an equilateral pentagon?

In contrast, the regular pentagon is unique, because it is equilateral and moreover it is equiangular (its five angles are equal; the measure is 108 degrees).

Which angles are congruent in a pentagon?

So, the sum of the interior angles of a pentagon is 540 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent).

How many right angles does a pentagon have?

three right angles
So a pentagon has a maximum of three right angles, as shown.

Can a pentagon have more than two 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. Its area, in this case, given side length s, is the sum of the areas of a square and an equilateral triangle, each with side length s: A pe…

How many sides does an equilateral pentagon have?

In geometry an equilateral pentagon is a polygon with five sides of equal length. Its five internal angles, in turn, can take a range of sets of values, thus permitting it to form a family of pentagons. The requirement is that all angles must add up to 540 degrees and must be between 0 and 360 degrees but not equal to 180 degrees.

How are the angles of an equilateral triangle congruent?

Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral. Created by Sal Khan. This is the currently selected item. Want to join the conversation? Posted 7 years ago.

What are the properties of a regular pentagon?

Regular Pentagons: The properties of regular pentagons: All sides are the same length (congruent) and all interior angles are the same size (congruent). Correspondingly, what does it mean to be congruent? The adjective congruent fits when two shapes are the same in shape and size.
