WebIn geometry, the isosceles triangle formulas are defined as the formulas for calculating the area and perimeter of an isosceles triangle. Area = 1/2 × Base × Height. Area = b 2√a2 − b2 4 b 2 a 2 − b 2 4. Area = 1/2 ×abSinα. (Here a and b are the lengths of two sides and α is the angle between these sides.) WebThe Pythagorean Theorem: This formula is for right triangles only! The sides, a and b, of a right triangle are called the legs, and the side that is opposite to the right (90 degree) angle, c, is called the hypotenuse. This formula will help you find the length of either a, b or c, if you are given the lengths of the other two.

WebThe Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C). WebSides of Triangle Formula. Each side of a triangle is represented by a straight line. These lines meet each other to form three vertices. Pythagoras theorem is applied to determine the sides of any right-angled triangle. When some side lengths and other angles are provided, we apply the cosine law or the sine law to get the length of any side ...
