Jawaban:

There are six fundamental concepts of trigonometry: triangles, right triangles, angles, angle measure, trigonometric functions, and trigonometric identities.

Example 1 - Triangles: A triangle is a three-sided polygon with three angles.

Example 2 - Right Triangles: A right triangle is a triangle with one 90 degree angle.

Example 1 - Angles: An angle is formed by two lines that intersect at a given point.

Example 2 - Angle Measure: Angle measure is the measurement of an angle in terms of degrees or radians.

Example 1 - Trigonometric Functions: Trigonometric functions are mathematical equations that describe a relationship between angles and sides of a triangle.

Example 2 - Trigonometric Identities: Trigonometric identities are relationships between trigonometric functions that hold true for all angles.
