Question

$\Delta PQR$ is such that $\angle P=\angle Q=\angle R={60}^{\circ }$. Which of the following is true?

• A. Both $A\text{and}B$
• B. Neither $A\text{nor}B$
• C. $\Delta PQR$ is an equilateral triangle.
• D. $\Delta PQR$ is an acute-angled triangle.

Answer 1

The correct option is A Both $A\text{and}B$

In $\Delta PQR$, since all the angles are acute, it is an acute-angled. Also, since all the angles are equal, it is an equilateral triangle.
