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.
