Polygons: Angles, Perimeter & Area

What We'll Learn

Here's what we'll learn today!

Polygons are the number-one tested topic on the ISEE — get comfortable with area and perimeter formulas for rectangles, parallelograms, and trapezoids.

Topics we'll cover

Rectangles (A = lw)
Parallelograms (A = bh)
Trapezoids (A = ½h(b₁+b₂))
Regular polygons
Interior angle sum = (n-2) × 180°
