The HA theorem, also known as the Hypotenuse-Angle (HA) theorem, is a result in geometry that relates the lengths of the sides of a right triangle to one of its acute angles.
According to the HA theorem, if we have a right triangle with one leg of length ‘a’, the hypotenuse of length ‘c’, and an acute angle opposite the leg of measure ‘θ’, then the following relationship holds:
sin(θ) = a / c
In other words, the sine of the acute angle θ is equal to the ratio of the length of the leg ‘a’ to the length of the hypotenuse ‘c’. This theorem is derived from the definition of the sine function in trigonometry, which relates the ratios of side lengths in a right triangle to its angles.
The HA theorem is useful for solving various problems involving right triangles, such as finding the length of a side or determining an angle given certain side lengths. It is a fundamental concept in trigonometry and plays a significant role in many applications of mathematics, such as engineering, physics, and navigation.
