relation between arc, radius and central angle. Proof of the trigonometrical ratios of complementary angles
Relation Between Arc Radius And Angle Arc length = [radius • central angle (radians)] Arc length = circumference • [central angle (degrees) ÷ 360] Proof of the trigonometric ratios of complementary allied angles Two acute angles are complementary to each other if their sum is equal to 90°.
