If two sides of a triangle are unequal, the measure of the angle opposite to the longer side is greater than the measure of the angle opposite to the shorter side.
If two angles of a triangles are unequal, then the side opposite to the greater angles is longer than the side opposite to the smaller angle.
No two angles of a scalene triangle are congruent.
