BD > CD Given

If one side of a triangle (BD) is longer than another side (CD), then the angle opposite the longer side has a greater measure than the angle opposite the shorter side.

If an angle is an exterior angle of a triangle, then its measure is greater than either of its corresponding remote interior angles.

If one angle of a triangle ( ) has a greater measure than another angle, then the side opposite the greater angle is longer than the side opposite the lesser angle ( ).
