Question

The angles of a right angled triangle are

• A. acute, acute, obtuse.
• B. acute, right, right.
• C. right, obtuse, acute.
• D. acute, acute, right.

Answer 1

The correct option is D acute, acute, right.

A right angled triangle is triangle, with one angle equal to ${90}^0$. The sum of remaining two angles is equal to ${90}^0$
$[\because$ sum of all the angles of a triangle is ${180}^0]$
So, each of the remaining angles is less than ${90}^0$
$⟹$ The angles of a right angled triangle are acute, acute, right.
