Example From Class 7 Chapter 7 Congruence of Triangles
| Ques. In the figure below, AB and CD bisect each other at O. Find the three pairs of equal parts in two triangles AOC and BOD.
Ans. From the figure, Sides AB and CD bisect each other at O AO = BO and OC = OD Since ∠ AOC and ∠ BOD are vertically opposite angles formed by the intersection of the line segments AB and CD, we can say that ∠AOC = ∠BOD Hence, the equal parts of the two triangles AOC and BOD are, AO = BO, OC = OD and ∠AOC =∠BOD (vertically opposite angles). |
