Question

Help pleasee

Use ∆BCA to answer the question that follows.
The two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles.
Statement Justification
Draw an altitude from point C to
Let = a
= b
= c
= h
= x
= y
y + x = c

a2 = cy; b2 = cx
a2 + b2 = cy + b2
a2 + b2 = cy + cx
a2 + b2 = c(y + x)
a2 + b2 = c(c)
a2 + b2 = c2

Which is NOT a justification for the proof?

Addition Property of Equality

Pythagorean Theorem

Pieces of Right Triangles Similarity Theorem

Cross Product Property
