This triangle has exactly two sides.

• A. Scalene triangle
• B. Isosceles triangle
• C. Equilateral triangle
• D. Acute triangle

Answer 1

The correct option is B

Isosceles triangle

Isosceles triangle has two equal angles and two equal sides.

Hence, option (b) is correct.

Scalene triangle has no similar angles and has unequal sides. So, option (a) is incorrect.

Equilateral triangle has all sides and all angles are equal and each angle is equal to $60°$. So, option (c) is incorrect.

Acute triangle has the value of all angles less than $90°$.So, option (d) is incorrect.
