• B. Isosceles triangle
• C. Right-angled triangle
• D. Obtuse-angled triangle

Answer 1

Answer: (A), (B), (C)

Right-angled triangle

The triangle having two of its sides as equal are isosceles triangles.

And, the triangle having one of its angle as ${90}^o$ is known as right-angled triangle.

The triangle whose two sides are equal and one of its angles is of ${90}^o$ is known as right-angled isosceles triangle.

Hence, the above triangle is right angled and isosceles or right-angled isosceles triangle.
So, option $\left(a\right)$, $\left(b\right)$ and $\left(c\right)$ are correct.
