1. What are trigonometric complementary angles?
A right triangle is one in which one of the angles is a right angle, such as 90 degrees. The longest side of a right triangle is the side opposite the right angle, which is known as the hypotenuse. The base is the horizontal side of the right angle that is parallel to the plane. The perpendicular is the side that is 90 degrees from the base. The total of the other two angles in a right triangle, except the right angle, equals 90 degrees. The Pythagorean theorem asserts that "the square on the longest side is equal to the sum of the squares on the other two sides" for all right triangles.
2. What are trigonometric ratios?
Trigonometry is a discipline of mathematics concerned with the measurements of a triangle's sides and angles, particularly those of a right triangle. The angles of a right triangle are represented by six trigonometric ratios in terms of their sides. There are two angles in every right triangle that are not 90 degrees. If any angle other than a right angle is designated as angle 'A' in a right triangle, the side next to angle 'A' that is not a hypotenuse is referred to as the adjacent side or base, and the side opposite to angle 'A' is referred to as the opposite side or perpendicular.
3. Explain the derivation of Trigonometric Ratios of Complementary Angles?
If the total of two angles equals 90 degrees, they are said to be complimentary. The value obtained by subtracting any angle from 90 degrees is the complement of that angle. The total of the other two angles in a right triangle, except the right angle, equals 90 degrees. As a result, these two angles are known as complementary angles.
Consider a right triangle ABC with a right angle at B to get the Trigonometric Ratios of Complementary Angles formula. If angle "C" is used as the reference angle, the angle "A" is the complement of angle "C." i.e. angle at point 'A' = 90 degrees -
The opposing side is 'AB' and the adjacent side is 'BC' when " is used as the reference angle. AC is the hypotenuse of a right triangle because it is opposite the right angle.
