Interactive simulation the most controversial math riddle ever! Solving SSA Triangles "SSA" means "Side, Side, Angle" "SSA" is when we know two sides and an angle that is not the angle between the sides. Find the measure of each marked angle. Hence z + y = 180 Solve for y y = 180 - z = 180 - 128 = 52° The sum of the interior angles in the angle on the left is equal to 180. Proving trigonometric identities worksheet. Right.
