measure of the sum of its interior angles?
b. Pre-ectivity 2. Finding the sum of the exterior angles of a convex polygon by completing
the given equations based on the given illustrations.
1. Given: A RED with the given
measure of its interior angles.
Find the sum of its exterior angles
by completing the given equations.
if mLDRE = 80- then mZSRD =
60°
if MLRDE = 60°, then M.BDE =
if mZRED = 40°, then mZREP
