Calculate sides of triangle from angles
WebAnother way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. ... Using the law of sines makes it possible to find unknown angles and sides of a triangle given enough information. Where sides a, b, c, and angles A, B, C are as depicted in the above calculator, the law of sines can be ... WebApr 30, 2011 · Copy. The angles of a triangle don't change no matter how big or small the triangle is, so finding the length is impossible, but you can find the ratio of the triangle from this, as so: -Set one side of the triangle equal to 1. -Use this information to solve (capital letters representing angles, lower-case representing sides) A= 30 a= 1. B= 60 b=.

WebJul 4, 2024 · This forms two 30-60-90 triangles. The side opposite the 30° angle is half of a side of the equilateral triangle, and hence half of the hypotenuse of the 30-60-90 triangle. The length of the remaining side follows via the Pythagorean Theorem. “And I take the triangle COY with angles 30-60-90. Since OC = 1, then OY = (√3)/2, and CY = 1/2.
