Question

In a right angled triangle, the angles other than the right angle are _______ .

• A. obtuse angles
• B. supplementary
• C. acute angles
• D. greater than right angles

Answer 1

The correct option is C

acute angles

$\text{The sum of the angles of a triangle}\text{is}{180}^o.$

$\text{Hence, if one angle of a right angled triangle}\text{is}{90}^o,\text{then the sum of other two angles}\text{should be equal to}{90}^o.$

$\text{So, each angle should be}\text{less than}{90}^o.$

$\text{So, in a right angled triangle, the}\text{angles other than the right angle are}\text{acute angles.}$
