Question

Mark the correct answer.

A triangle that has one angle greater than $90°$ but less than $180°$.

• A. Right triangle
• B. Obtuse triangle
• C. Equilateral triangle
• D. Acute triangle

Answer 1

The correct option is B

Obtuse triangle

A triangle that has atleast one angle greater than $90°$ but less than$180°$ is called an obtuse angled triangle.

Hence option (b) is correct.

In a right triangle, the largest angle is $90°$. So it cannot be obtuse angled triangle. So option (a) is incorrect.

In an equilateral triangle, all angles are equal and have the value $60°$. So option (c) is incorrect.

In an acute triangle, all angles should be less than $90°$. So option (d) is incorrect.
