How to Calculate Triangles Isosceles
What is Triangles Isosceles?
An isosceles triangle has two equal sides and two equal base angles. The perpendicular from the apex to the base also bisects the base (axis of symmetry). Isosceles triangles appear frequently in architecture, art, and engineering.
Formula
- h
- √(a² − (c/2)²) where c is the base — √(a² − (c/2)²) where c is the base
Step-by-Step Guide
- 1Two equal sides (legs): a = b
- 2Height h = √(a² − (c/2)²) where c is the base
- 3Area = ½ × base × height
- 4Apex angle = 180° − 2 × base angle
