Question

Medal And Fan!!!!!! for the best answer!!

Given: ΔABC is a right triangle.

Prove: a2 + b2 = c2


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?

Answer 1

Pieces of Right Triangles Similarity Theorem
Side-Side-Side Similarity Theorem
Substitution
Addition Property of Equality

Answer 17

I think...

Answer 18

hey its a cause there is no usage of that property rather substution and euality property is used as we have equated the respective sides to a,b and c and then used the equality theorm to prove the pythagoras theorem. answer is a.
