Key Concepts

Properties of Right Triangles

A right triangle is characterized by one 90° angle, which establishes relationships between the sides and angles. The sum of the angles in any triangle is 180°, so in a right triangle the two non-right angles must add up to 90°. This property allows for the determination of an unknown angle when one acute angle is given.

Trigonometric Ratios

Trigonometric ratios such as sine, cosine, and tangent relate the angles of a right triangle to its side lengths. By definition, the sine of an angle is the ratio of the length of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side. These relationships are essential in solving for unknown sides or angles in right triangles.

Pythagorean Theorem

The Pythagorean theorem states that in a right triangle the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is a crucial tool for calculating the length of an unknown side when the other two side lengths are known.

Rounding and Approximation Techniques

When solving problems that involve trigonometric calculations and measurements, rounding is often necessary to express the final results in a practical form. This includes rounding side lengths to a specified number of decimal places and angles to the nearest degree or tenth of a degree, ensuring that the answers are both precise and usable in application.
