Question

In the given figure, $\text{ABCD}$ is a rhombus in which diagonals $\text{AC}$ and $\text{BD}$ intersect at $\text{O}$. Then $\angle \text{AOB}$ is

• A. ${60}^{\circ }$
• B. ${90}^{\circ }$
• C. ${80}^{\circ }$
• D. ${45}^{\circ }$

Answer 1

The correct option is B ${90}^{\circ }$

The diagonals of a rhombus intersect each other at right-angles.

So, $\angle$ AOD $={90}^{\circ }$.
