Question

In $\Delta RST$, $RS$ = 5 cm, $\angle SRT={45}^{\circ }$ and $\angle RST={45}^{\circ }$. Which criterion can be used to construct $\Delta RST$?

• A. A.S.A. criterion
• B. S.A.S. criterion
• C. S.S.S. criterion
• D. A.A.S. criterion

Answer 1

The correct option is A

A.S.A. criterion

Clearly, from the figure two angles and the included side are given. So, A.S.A. criterion can be used to construct $\Delta RST$.
