Question
Which is true?
✓
Answer
- A triangle can have two acute angles.
Solution:
We know that, by the angle sum property,
the sum of all the angles of a triangle is 180° ...(i)
So, if two angles are right angles, then their sum is 180°.
So, the measure of the third angle is zero, which is not possible.
Thus, (a) is not true.
