What is a polygon that has all angles congruent?
website feedback. Polygon. A closed plane figure for which all sides are line segments. The name of a polygon describes the number of sides. A polygon which has all sides mutually congruent and all angles mutually congruent is called a regular polygon.
What is a polygon with all sides?
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
What do you call polygons that have all sides and angles congruent?
regular polygon
A regular polygon has congruent angles and congruent sides. Any polygon can be a regular polygon. Look at the regular polygons below. As you can see, a regular hexagon has six congruent sides and six congruent angles.
Are all polygons congruent?
Definition: Polygons are congruent when they have the same number of sides, and all corresponding sides and interior angles are congruent. All corresponding sides are the same length, All corresponding interior angles are the same measure.
Which polygon does not have congruent sides?
A scalene quadrilateral is a four-sided polygon that has no congruent sides.
What is a congruent figure?
Two shapes that are the same size and the same shape are congruent. They are identical in size and shape. …
What is a congruent Pentagon?
We get. So, the sum of the interior angles of a pentagon is 540 degrees. Regular Pentagons: The properties of regular pentagons: All sides are the same length (congruent) and all interior angles are the same size (congruent).
What polygon has 20 sides?
A 20-sided polygon is called an icosagon. Along with having 20 sides, all icosagons have 20 interior angles that add up to a total of 3240 degrees. Regular icosagons have sides of equal length and identical interior angles, each of which measures 162 degrees. Irregular icosagons on the other hand, have sides and angles of varying lengths.
Does polygon have six sides?
A six-sided polygon is called a hexagon. A polygon is an enclosed figure with straight lines that do not cross over one another. Polygons do not necessarily have equal sides. A convex polygon has all angles pointing outward, but in a concave polygon, some angles can point inward.
Do polygon usually have more sides or more angles?
A polygon should always have the same ratio of sides to angles. Every time you add a side to a polygon, a new angle is created. Every polygon has the same number of sides as it has angles. (Their “ratio” is always 1:1.)
What polygon has equal sides and equal angles?
A polygon with equal sides and equal angles is called a regular polygon. A regular triangle is called an equilateral triangle. In case of an equilateral triangle, the angles are also equal i.e., each angle of an equilateral triangle is 60º.
