Q:
# What is a polygon with all of its sides and angles congruent?

A:
### Quick Answer

**An angle with all of its sides and angles congruent is a regular polygon.** The term "congruent" means exactly equal in shape or size, while a polygon is defined as a closed figure made up of sides that are line segments.

Every square, by definition, has four sides of equal length and four right angles measuring 90 degrees each. Because the sides and angles are congruent, a square also classifies as a regular polygon.

An equilateral triangle is considered a regular polygon because it has three congruent sides and three angles measuring 60 degrees each. The right triangle is not a regular polygon because it has one 90-degree angle and two smaller angles that add up to 90 degrees. In an isosceles right triangle, these two smaller angles both measure 45 degrees each. In a 30-60-90 triangle, one of the smaller angles measures 30 degrees and the other measures 60 degrees.

## Is a circle a polygon?

A:

Full Answer >**A circle is not a polygon because it does not conform to the definition of a polygon.**The definition of a polygon is a closed figure formed by straight lines or straight sides. Although the circle is a closed figure, it is not formed by straight line segments.Filed Under: -
Q:
## How do you find the arc of a circle?

A:To find the arc of a circle, divide the angle subtended at the center of the arc by 360 degrees, then multiply the answer by the circumference of the circle. You need to know the value of pi and must have a protractor to complete this task.
