# Trigonometric Ratios of Complementary Angles

If the sum of two angles is then, it is called Complementary Angles. In a right-angled triangle, one angle is, so the sum of the other two angles is also or they are complementary angles.so the trigonometric ratios of the complementary angles will be –

Sin = cos A,

cos = sin A,

Tan = cot A,

Cot = tan A,

Sec = cosec A,

Cosec = sec A
