WebThe Pythagorean trigonometric identities in trigonometry are derived from the Pythagoras theorem.The following are the 3 Pythagorean trig identities. sin 2 θ + cos 2 θ = 1. This can also be written as 1 - sin 2 θ = cos 2 θ ⇒ 1 - cos 2 θ = sin 2 θ; sec 2 θ - tan 2 θ = 1. This can also be written as sec 2 θ = 1 + tan 2 θ ⇒ sec 2 θ - 1 = tan 2 θ; csc 2 θ - cot 2 θ = 1. WebMar 31, 2024 · The Pythagorean Theorem can be used to find the length of one side of a right triangle (a triangle with a 90-degree angle): if you have the lengths of the perpendicular sides a and b, for example, you plug the values into the formula a^2+b^2=c^2. Solve for c and you can find the length of the remaining side (the hypotenuse).
