Key Concepts

Trigonometric Ratios

Trigonometric ratios—sine, cosine, and tangent—relate the angles of a right triangle to the ratios of its sides. These ratios provide a method for solving for unknown side lengths or angles when certain other measurements in the triangle are known. They are essential tools in both pure and applied mathematics for analyzing right triangles.

Right Triangle

A right triangle is a triangle that includes one angle measuring 90 degrees. Understanding the properties of right triangles is crucial because they allow the application of certain mathematical tools—such as the Pythagorean theorem and trigonometric ratios—that simplify the process of solving for unknown side lengths or angles.

Pythagorean Theorem

The Pythagorean theorem is a fundamental principle in Euclidean geometry, particularly applicable to right triangles. It states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This theorem provides a direct method for calculating an unknown side length when the other two side lengths are known.
