Question

Construct a triangle $△MNO$ where $\angle M={70}^o,\angle N={60}^o$ and side $MN=7cm$.

Answer 1

Steps of construction :

1) Draw a line segment $MN=7cm$.

2) Make $\angle AMN={70}^o$.

3) Make $\angle BNM={60}^o$.

4) Let $AM$ and $BN$ intersect at $O$.

Then, $△MNO$ is the required triangle.
