Question

Recall the following definitions Two angles are called supplementary if they share a side and the other two sides are opposite rays. The segment PR is called the sum of segments AB and CD if there exists a point Q on the segment PR (i.e. on the line PR between P and R) such that segment PQ is congruent to segment AB and segment QR is congruent to segment CD In a similar way, give a definition of: (a) vertical angles. Two angles are called vertical if .. (b) Difference of two segments. The segment PR is called the difference of segments AB and CD if (c) Sum of two angles. Angle POR is called the sum of angles AXB and CYD if... (You can use the term interior of an angle here.)
