Consider the diagram of a square within a square shown below:
Write an expression using the lengths from the diagram for each of the following:
i. Area of the large square in terms of a and b:
ii. Area of the small square:
iii. Total area of the four triangles:
Question 4
4.
The Pythagorean Theorem states that if a right triangle has legs of length a and b and hypotenuse of length c, then a squared plus b squared equals c squared. Figures 1 and 2 represent key ideas in proof of the Pythagorean Theorem.
Create and outline a proof for the Pythagorean Theorem based on figure 1 and figure 2, by ordering the following 8 statements into a logical sequence.
The total area of the large square in Figure 2 is
The two large squares have the same area because they are congruent
Start with two large squares with sides of length (a+b)
Subdivide the large square in figure 2 into four right triangles with legs a and b and a square in the middle with side-length C.
The total area of the large square in figure 1 is
Subdivide the large square in figure 1 into a square with side-lengths a, a square with side-lengths b, and two rectangles with side-lengths a+b.
