Trigonometry is the oldest topic in the history of mathematics. This topic is mainly related to the sides of triangles and the angles of different figures. Unknown sides and angles are studied using trigonometry formulas or trigonometric identities. In trigonometry, angles are measured in degrees or radians.
The important angles are 0°, 30°, 45°, 60°, and 90°. Don't be the fear of this topic remains in the mind of the students, we have sharing practice questions here related to Trigonometry Questions and Answers for the competitive exams. Start your practice below with some important questions for you.
