The area of triangle formulas is, A=1/2(b*h) Here b is the base of a triangle. h is the height of a triangle. One another way to find the area is the Heron's formula. It gives the area in terms of the three sides of the triangle. It is given by the following formula: Area A = √(s(s - a) (s - b) (s - c)) Here, s is the semi perimeter of the triangle and s = (a+b+c)2. The area of triangle when two sides and one angle are given is given by the following formula: Area A= (ab sin C)/2 The above formula says that area of a triangle is the half of the product of two side values and one angle.

Below are some examples based on area of a triangle Example 1: Find the area of scalene triangle with a base of 15 cm and a height of 4 cm Area = 12 (b*h) Substitute the values of base and height. Then we get, Area = 12 (15*4) = 12 (60) = 30 cm2
List of Pythagorean Triples Pythagorean Triples In Geometry of right triangles, Pythagoras theorem plays a major role which states that "The Square of the Hypotenuse is equal to the sum of the squares of the other two sides". A set of three positive whole numbers a, b, and c that are the lengths of the sides of a right triangle which satisfy the equation from the Pythagorean Theorem a2 + b2 = c2 is called a pythagorean triples. Examples of Pythagorean Triples A Pythagorean triple is commonly written as (a, b, c). The smallest example of a Pythagorean triple is a = 3, b = 4, and c = 5. We can verify that (3)2 + (4)2 = 9 + 16 = 25 = (5)2.
A primitive Pythagorean triple is a triple in which a, b and c are co prime. In other words, the greatest common divisor of the three numbers a ,b and c should be only 1. Imprimitive Pythagorean triple can be obtained from primitive Pythagorean triples, by multiplying each of a, b, and c by any positive whole number k > 1. This is because a2 + b2 = c2 if and only if (ka)2 + (kb)2 = (kc)2. Thus, If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k. For example, (6,8,10) and (9,12,15) are imprimitive Pythagorean triples obtained from the Pythagorean triple (3,4,5) by multiplying it with 2 and 3 respectively. Pythagorean Triples Formula All the pythagorean triple can be derived from a simple formula. Let m and n be two positive integers, with m < n. Then n2 - m2, 2mn, and n2 + m2 is a Pythagorean triple. Algebraically, it is easy to check that the sum of the squares of the first two is the same as the square of the last one.
