A quadrilateral is a four sides polygon with 4 angles. In this topic we will learn about the different kinds of quadrilaterals that can exist!
A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. In this chapter we will learn about two different kinds of parallelograms, the rhombus and the rectangle.
Polygons are many-sided figures, with sides that are line segments. Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. In this topic we will learn about the exterior angle property, interior angle property, and we will also practice with some exercises related to polygons.
