Question

Given: ∆BCA is a right triangle.
Prove: a2 + b2 = c2

Which is NOT a justification for the proof?

Substitution

Addition Property of Equality

Transitive Property of Equality

Distributive Property of Equality

Answer 1

Statement

Justification
Draw an altitude from point C to Line Segment AB


Let Line Segment BC= a
Line Segment CA= b
Line Segment AB= c
Line Segment CD= h
Line Segment DB= x
Line Segment AD= y


y + x = c


c over a is equal to a over y; c over b is equal to b over x


a2 = cy; b2 = cx


a2 + b2 = cy + b2


a2 + b2 = cy + cx


a2 + b2 = c(y + x)


a2 + b2 = c(c)


a2 + b2 = c2

Answer 2

^it wasnt supposed to say Justification, cuz there aint any... sry

Answer 3

help?? please...

Answer 4

I beleive its Transitive Property of Equality
