Question

Which of the following given triangles are right-angled triangles?

• A. $A$ and $D$
• B. $B$ and $C$
• C. $A$, $B$, $C$ and $D$
• D. None

Answer 1

The correct option is B $B$ and $C$

We know that right-angled triangles are those triangles which have one of the three angles as ${90}^o$.

In the given figure, we can see that $B$ and $C$ triangles have one angle of ${90}^o$ so $B$ and $C$ are right-angled triangles
