Polygons can be regular or irregular in shape. A polygon is a closed 2D shape with at least three sides. A regular polygon is a polygon with all equal sides and angles. An irregular polygon is a ...

The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Sum of interior angles = 180(n – 2) where n is the number of sides In a regular polygon all the angles are ...

Polygons are two dimensional shapes with straight sides. They can be described by the number of sides they have and whether the shape is regular or irregular. Where the straight sides of the polygon ...

Interior angles in a triangle add up to 180˚. Triangles close triangleA polygon with three straight sides. have three sides, therefore they have three angles. Interior angles in a triangle sum to a ...

A polygon is simply a shape with three or more sides and angles. Quadrilaterals are 2D shapes with four sides and angles. There are six special quadrilaterals with different properties. A rectangle ...

The simplest polygon is a triangle (a three-sided shape). Polygons of all types can be regular or irregular. A regular polygon has sides of equal length, and all its interior angles are of equal size.

A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other. A parallelogram has two pairs of equal sides. It has two ...
