Question 1132931: In isosceles triangle RST, RS=ST. Prove that angle SRP, the exterior angle at R, is congruent to angle STQ, the exterior angle at T. Answer by Alex.33(110) (Show Source):
You can put this solution on YOUR website! RS=ST
therefore angle R=angle T
therefore the exterior angle at R=the exterior angle at T
(180-angle R=180-angle T)
Hope this helps!
