The sum of the measures in degrees of the angles of a triangle is 180. www.erikthered.com/tutor pg. 1 SAT Math Given Facts & Formulas Below is a brief explanation of the formulas and figures on page 1. Note that on the test you only get what is on page 1, not the explanations below. The first row of diagrams on page 1 shows several important formulas related to triangles. The first triangle on the left shows how to calculate the area of any triangle, given the base b and the height h , using A = b · h/ 2. Note that any side can be the base, as long as the height goes from the base to the opposite corner.the height goes from the base to the opposite corner....
