A four-sided polygon with four congruent sides and four equal angles is a square
Any 8 sided polygon is called an octagon. If all of the sides and angles are equal, then it's called a regular octagon.
An isosceles trapezoid has a pair of parallel sides and a pair of equal base angles
A regular polygon has equal angles AND sides.
A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
trapezoid
A four-sided polygon with four congruent sides and four equal angles is a square
A rhombus, an equal sided parallelogram or an equal sided quadrilateral with no right angles.
An Isosceles triangle.
A four-sided polygon with all sides equal and no right angles would be a rhombus. A rhombus consists of two acute angles and to obtuse angles.
It is a 6 sided polygon with 6 equal sides and 6 equal interior angles
if the sides of the polygon are equal in length and the angles of the joining sides are equal in degrees then the polygon will become more circular. Compare a 4 sided square to an 8 sided octogon (stop sign shape)
Any 8 sided polygon is called an octagon. If all of the sides and angles are equal, then it's called a regular octagon.
So, the Sum of the interior angles for a 21 – sided polygon is equal to 3420°.
An isosceles trapezoid has a pair of parallel sides and a pair of equal base angles
A regular polygon has equal angles AND sides.
Polygon is a two dimensional figure that has three or more sides. Polygons are classified by their number of sides. Three sided is a triangle. A four sided figure is a quadrilateral. A five sided figure is a pentagon and so forth. The number of angles it has is equal to the number of sides.A polygon usaally has 5sides
