What follows are over three dozen of the most important geometry formulas, theorems, properties, and so on that you use for calculations. If you get stumped while working on a geometry problem and can't come up with a formula, this is the place to look. Triangle formulas Sum of the interior angles of a triangle: 180º Area: A good way to test your knowledge. Version 4.2 Page 5 of 137 August 26, 2023 Chapter 1 Basic Geometry An intersection of geometric shapes is the set of points they share in common. l and m intersect at point E. l and n intersect at point D. The formulas used for finding dimensions, perimeter, area, surface area, volume, etc. of 2D and 3D geometric shapes are known as geometry formulas. 2D shapes consist of flat shapes like squares, circles, and triangles, etc., and cube, cuboid, sphere, cylinder, cone, etc are some examples of 3D shapes. This handout is intended as a review of basic geometric formulas and properties. For further or more advanced geometric formulas and properties, consult with a SLAC counselor. Square: Perimeter: P = 4s or 2s + 2s Area: A = s2 Rectangle: Perimeter: P = 2w + 2l Area: A = l × w Triangles: Perimeter: P = a + b + c Area: A = (1/2) × b × h ss s l c h
