Which is true?
- ✓A triangle can have two right angles.
- BA triangle can have two obtuse angles.
- CA triangle can have two acute angles.
- DAn exterior angle of a triangle is less than either of the interior opposite angles.
✓
Answer
Correct option: A.
A triangle can have two right angles.
We know that, by the angle sum property,
the sum of all the angles of a triangle is $180^\circ ...(i)$
So, if two angles are right angles, then their sum is $180^\circ .$
So, the measure of the third angle is zero, which is not possible.
Thus, $(a)$ is not true.
