Question

Observe the figures below and write the type of the triangle based on its angles.

Answer 1

In $\Delta PQR,$ $\angle Q={90}^{\circ }$ (a right angle)

Therefore,$\Delta PQR$ is a right-angled traingle.

In $\Delta XYZ,$ $\angle Y={125}^{\circ }$ (an obtuse angle)

Therefore, ​$\Delta XYZ$ is an obtuse angle triangle.

In $\Delta LMN,$ all angles are acute angles.

Therefore, ​$\Delta LMN$ is an acute-angled triangle.
