MCQ
If all the angles of a triangle are acute, the triangle is called:
- AObtuse$-$angled
- ✓Acute$-$angled
- CRight$-$angled
- DNone of these
✓
Answer
Correct option: B.
Acute$-$angled
An equilateral triangle is a triangle with all three angles and sides equal. If all a triangle's angles are equal, they all must measure $60$ degrees, adding up to $180$ degrees total. Since all angles are acute, or less than $90$ degrees, an equilateral triangle is also an acute triangle.
