Question

This is just one of the Figures, I will send you a picture of the whole entire question.

Answer 1

The combined area of the shaded triangles in figure 1 is equal to the combined area of the shaded triangles in figure 2. The area of the unshaded square in figure 1 can be represented by

$c^2$

The combined area of the two unshaded squares in Figure 2 can be represented by

$a^2+b^2$

The areas of the equares in figure 1 and figure 2 show that

$a^2+b^2=c^2$
