Are all triangles with three pairs of equal corresponding angles congruent?
Are all triangles with three pairs of equal corresponding angles congruent? Because three pairs of sides and three pairs of angles are all congruent and they are corresponding parts, this means that the two triangles are congruent. How do you determine if two triangles are congruent? SAS stands for “side, angle, side” and means that […]
