Question 1195538: Let XOY be an angle and PZ be an interval. Construct an arc with centre O meeting OX at A and OY at B. With the same radius, construct an arc with centre P, meeting PZ at F. With radius AB and centre F, construct an arc meeting the second arc at G.
(a) Prove that triangle AOB is congruent to triangle GPF.
(b) Hence, prove that Angle AOB = Angle FPG.

.

(a)  Triangle AOB is congruent to triangle GPF due to SSS-test of congruency for triangles,

     since they have congruent (equal) sides by construction.



(b)  Angle AOB = Angle FPG  as the corresponding angles in congruent triangles AOB and GPF.
