Question

Mark the correct answer.

A triangle that has no equal sides.

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

Answer 1

The correct option is A

Scalene triangle

Scalene triangle has no similar angles and has unequal sides.

Hence, option (a) is correct.

Isosceles triangle has two equal angles and two equal sides. Hence option (b) is incorrect.

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

Acute triangle has all the angles less than 90°. So, option (d) is not the exact answer to the question asked although some scalene triangles can be acute triangles. Hence option (d) is incorrect in this context.
