Question

In $△ABC$, if $AB=7$ cm, $\angle A={40}^o$ and $\angle B={70}^o$, which criterion can be used to construct this triangle?

• A. ASA
• B. SSS
• C. SAS
• D. RHS

Answer 1

The correct option is A ASA

Given : In a triangle $ABC,AB=7cm,\angle A={40}^o$ and $\angle B={70}^o$

So, here we know two of the angles and a side including these angles.

Hence, Angle Side Angle i.e ASA criterion can be used to construct this triangle.

706o
