Find angle of triangle with 3 sides
WebA triangle has three sides, three vertices, and three interior angles. The angle sum property of a triangle states that the sum of the three interior angles of a triangle is always 180°. Observe the triangle PQR given above in which angle P + angle Q + angle R = 180°. WebTriangle 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- a2 = b2 +c2 − 2bc.cos(A) a 2 = b 2 + c 2 - 2 b c. cos ( A) b2 = a2 +c2 − 2ac.cos(B) b 2 = a 2 + c 2 - 2 a c. cos ( B)
