Step 1: Enter the values of any two angles and any one side of a triangle below which you want to solve for remaining angle and sides. Triangle calculator finds the values of remaining sides and angles by using Sine Law. Sine law states that a sinA = b sinB = c sinC a sin A = b sin B = c sin C Cosine law states that-

Where a and b are two sides of a triangle, and c is the hypotenuse, the Pythagorean theorem can be written as: a 2 + b 2 = c 2. EX: Given a = 3, c = 5, find b: 3 2 + b 2 = 5 2 9 + b 2 = 25 b 2 = 16 b = 4. Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. Using the law of sines makes it.
Ex 11.2, 6 Let ABC be a right triangle AB = 6 cm, BC = 8 cm, B = 90
Angles Add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3.

In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

The 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).

Example 6 In an isosceles triangle ABC with AB = AC Examples
The perimeter of a triangle is equal to the sum of all the sides of the triangle, and the formula is expressed as, Perimeter of a triangle formula, P = (a + b + c), where 'a', 'b', and 'c' are the three sides of the triangle. The equilateral triangle formula for perimeter is, Perimeter of equilateral triangle = (a +a + a) = 3a.
