Question

In the adjoining figure, find the total number of right angled triangles.

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3


In the given figure,
$\angle DAB={90}^{\circ }$. Hence, $△ADB$ is a right angled triangle.

$\angle ACD={90}^{\circ }$. Then, $△ACD$ is also a right angled triangle.

Similarly, $\angle ACB={90}^{\circ }$. So, $△ACB$ is also a right angled triangle.

So, there are three right angled triangles in the given figure.
