👉 The term "semitrigonometry" is often used in geometry to describe a method of measurement that uses trigonometric functions such as sine and cosine. This method involves using a right triangle with two known angles (in this case, the angle between the sides) and one unknown side length, called the hypotenuse. The goal is to find the third side of the triangle by applying the trigonometric function to the known values and solving for the missing side length.
