Question
Lyndsey was using the diagrams and Angle-Angle Triangle Similarity to prove the Pythagorean Theorem.
"We can use the Angle-Angle Triangle Similarity Theorem to show that all 3 triangles are similar. Because the triangles are similar,
corresponding side lengths are in the same proportion.
Because the largest triangle is similar to the smaller triangle, =.
a
Because the largest triangle is similar to the middle triangle, =.
We can rewrite these equations as a? = cd and b2 = ce.
We can add the 2 equations to get that a2 + b2 = cd + ce or a? + b2 = c(d + e). From the original diagram we can see that d + e = c, so
a² + b2 = c(c) or a2 + b2 = c²."
