Triangles come in different shapes and sizes, such as right triangles, scalene triangles, and isosceles triangles. Finding the area of these triangles

A right triangle contains one 90-degree angle and is formed when two sides meet perpendicularly. Finding its area uses a simple formula derived from t

Triangles appear throughout everyday life—in architecture, art, engineering, and design. Knowing how to find a missing measurement of a triangle when

A parallelogram is a quadrilateral with two pairs of parallel sides. Its area can be calculated using a formula similar to that of a rectangle, but wi

When the area of a parallelogram and one dimension are known, the other dimension can be found by rearranging the area formula. This skill is used in

A kite and a rhombus are special quadrilaterals whose area can be found by splitting them into two triangles. Understanding this method prepares stude

Surface area describes how much space covers the outside of a three-dimensional object. Finding the surface area of a cube helps understand how its fa

Polygons can be drawn on a coordinate plane using ordered pairs. Studying polygons on a coordinate plane helps understand shapes, distances, and how g
