Learn the two important triangle formulas, the area of a triangle, and the perimeter of a triangle. These two formulas are applicable to all types of triangles. Understand the triangle formulas with derivation, examples, and FAQs.
The Triangle Formula are given below as, Perimeter of a triangle = a + b + c. \ [Area\; of \; a\; triangle= \frac {1} {2}bh\] Where, b is the base of the triangle. h is the height of the triangle. If only 2 sides and an internal angle is given then the remaining sides and angles can be calculated using the below formula:
Jan 18, 2024 · A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to: area = a × b / 2. For example, if we know only the right triangle area and the length of the leg a, we can derive the equation for the other sides: b = 2 × area / a
The formula works for all triangles. Note: a simpler way of writing the formula is bh/2. Example: What is the area of this triangle? (Note: 12 is the height, not the length of the left-hand side) Height = h = 12. Base = b = 20. Area = ½ × b × h = ½ × 20 × 12 = 120.
The area formulas for all the different types of triangles, like an area of an equilateral triangle, right-angled triangle, an isosceles triangle along with how to find the area of a triangle with 3 sides using Heron’s formula with examples are given below.

Triangle Formulas. In geometry, for every two-dimensional shape ( 2D shape ), there are always two basic measurements that we need to find out, i.e., the area and perimeter of that shape. Therefore, the triangle has two basic formulas which help us to determine its area and perimeter. Let us discuss the formulas in detail. Perimeter of Triangle.
