# The Pythagorean Theorem states that for a right-angled triangle 4ABC, as in ﬁgure, a2 =b2 + c2. Use this equation to prove that sin2 θ + cos2 θ = 1

## Question

## Solution 1

Sure, let's prove that sin²θ + cos²θ = 1 using the Pythagorean theorem.

Step 1: In a right-angled triangle, let's denote the sides as follows:

- The side opposite to angle θ as 'b'
- The side adjacent to angle θ as 'c'
- The hypotenuse as 'a'

Step 2: According to the Pythagorean theorem, we have Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
