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:
Triangle Formula. Area of a triangle is the region occupied by a triangle in a two-dimensional plane. The dimension of the area is square units. The formula for area is given by; Area = 1/2 x Base x Height. The perimeter of a triangle is the length of the outer boundary of a triangle. To find the perimeter of a triangle we need to add the ...
The two basic triangle formulas are the area of a triangle and the perimeter of a triangle. These triangle formulas can be mathematically expressed as; Area of triangle , A = [(½) b × h]; where 'b' is the base of the triangle and 'h' is the height of the triangle.
In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
Properties of a triangle help us to identify a triangle from a given set of figures easily and quickly. Learn about angle sum property, triangle inequality property, exterior angle theorem, etc with solved examples and practice questions.

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.
