An acute triangle is a figure where all three angles measure less than 90°.
1. All three interior angles measure less than 90°;
in ∆ABC, ∠ABC, ∠BAC, ∠ACB are ∠90°
Acute triangles are classified into three types: 1) acute scalene triangle, 2) acute isosceles triangle, and 3) acute equilateral triangles.
The differences between the types are given below:
Area (A) = ½ (b × h), where b = base and h = height
Perimeter (P) = a + b + c, where a, b, c are the three measures of three sides
