The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Using the image, let's consider a right triangle with sides of lengths a, b, and c, where c is the hypotenuse.
The first step in the proof is to draw squares on each side of the triangle. Here, we have squares with side lengths a, b, and c.
Then, we can observe that the large square, with side length a + b, contains four triangles congruent to the given right triangle. This is because the right triangle can be rearranged to perfectly fit into the large square.
Now, let's focus on the smaller squares. The square with side length a is divided into two congruent right triangles and a square with side length b. Similarly, the square with side length b is divided into two congruent right triangles and a square with side length a.
From this observation, we can conclude that the combined areas of the squares with side lengths a and b is equal to the combined area of the square with side length c. Mathematically, this can be represented as:
a^2 + b^2 = c^2
Therefore, the Pythagorean Theorem is proven using the image and the concept of rearranging and comparing areas of squares.
