#### Special right triangle - Wikipedia

"Angle-based" special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π / 2 radians, is equal to the sum of the other two angles.. The side lengths are generally deduced from the basis of the unit circle or other geometric methods.

Why the smaller angle? Because the inverse sine function gives answers less than 90° even for angles greater than 90°. By choosing the smaller angle (a triangle won't have two angles greater than 90°) we avoid that problem. Note: the smaller angle is the one facing the shorter side. Choose angle B: sin B / b = sin A / a. sin B / 5 = sin(49°) / 5.298... Did you notice that we didn't use a ...
