Class 10 Mathematics — Introduction to Trigonometry Important Questions with Answers (Long answers)

Class 10 Mathematics is still the CBSE board paper that rewards NCERT exercise lines more than imported entrance tricks. Real numbers (Euclid, fundamental theorem), quadratic formula, similar triangles, trigonometry identities, circles and surface area are the high-search clusters. This hub writes 150+ important questions with a hidden key so you can run a 20-question mock without scrolling a 40-screen PDF. No invented board date — only rationalized 2023–26 chapter names.

Introduction to Trigonometry — त्रिकोणमिति का परिचय

sin, cos, tan of 0°, 30°, 45°, 60°, 90° and identities sin²θ+cos²θ=1, 1+tan²=sec², 1+cot²=csc². Complementary relations: sin(90−θ)=cosθ. Do not invent 15° values unless an identity produces them. These MCQs are table-plus-identity, the board’s cheapest six marks if you are fluent. You are on Introduction to Trigonometry (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.

View the correct answer

sin, cos, tan of 0°, 30°, 45°, 60°, 90° and identities sin²θ+cos²θ=1, 1+tan²=sec², 1+cot²=csc². Complementary relations: sin(90−θ)=cosθ. Do not invent 15° values unless an identity produces them. These MCQs are table-plus-identity, the board’s cheapest six marks if you are fluent.

चार बिंदु: (1) NCERT परिभाषा/सूत्र/घटना। (2) एक उदाहरण या आरेख-विचार। (3) एक तुलना या कारण। (4) एक साधारण संख्यात्मक या उद्धरण यदि पाठ माँगता है।
निष्कर्ष: उत्तर अध्याय-सत्य रखें — बोर्ड की डेटशीट यहाँ नहीं गढ़ी गई।
