This means each interior angle of an equilateral triangle is equal to 60°. What is an Equilateral Triangle?Īn equilateral triangle is a regular polygon in which all the 3 sides are of equal length and the interior angles are of equal measure. The formula used for finding the area of a right triangle of base (b) and height (h) is, Area of a right triangle = 1/2 × base × height. Thus, the area of the scalene triangle, with a base 'b and height 'h' is expressed as Area of scalene triangle = 1/2 × b × h What is the Formula Used for Finding the Area of a Right Triangle? The area of a scalene triangle is half of the product of the base and the height of the triangle. No, an isosceles triangle can be an acute angle, right angle, or obtuse-angled triangle depending upon the measure of the angles it has. There are six types of triangles categorized on the basis of sides and angles as listed below: How many Types of Triangles are there in Maths? Perimeter of a triangle, P = (a + b + c) where 'a', 'b', and 'c' are the 3 sides of the triangle.Area of triangle, A = where 'b' is the base of the triangle and 'h' is the height of the triangle.These triangle formulas can be mathematically expressed as The two basic triangle formulas are the area of a triangle and the perimeter of a triangle. What are the Two Basic Triangle Formulas? It is a simple polygon in which the 3 vertices are joined with each other and it is denoted by the symbol △. In geometry, a triangle is defined as a two-dimensional shape with three sides, three interior angles, and three vertices.
