Answer 2

Answer:

1) Acute angled Triangle : It is a triangle, whose each angle is acute, i.e.,each angle is less than 90°.

2) Right angled Triangle : It is a triangle, whose one angle is a right angle, i.e., equal to 90°.

3) Obtuse angled Triangle : If one angle of a triangle is more than 90°, it is called an obtuse angled Triangle.
