Complementary Angles
What Are The Different Types Of Angles
What Are The Different Types Of Angles Angle: Two rays with a common end point form an angle. OA, OB are rays & O is end point. Types of AnglesIn geometry, angles can be classified according to the size (or magnitude) of the angle.Right angle: An angle whose measure is 90°, is called a right angle. Two lines that meet at a right angle are said to be … [Read more...] about What Are The Different Types Of Angles
Trigonometric Ratios Of Complementary Angles
Trigonometric Ratios Of Complementary AnglesWe know Trigonometric ratios of complementary angles are pair of angles whose sum is 90° Like 40°, 50°, 60°, 30°, 20°, 70°, 15°, 75° ; etc, Formulae: sin (90° – θ) = cos θ, cot (90° – θ) = tanθ cos (90° – θ) = sin θ, sec (90° – θ) = cosec θ tan (90° – θ) = cot θ, cosec (90° – θ) = sec … [Read more...] about Trigonometric Ratios Of Complementary Angles
