Question

Can someone help me with a review? The subject is on, "Proving Pythagoras and Proportionality"

Answer 1

Here is the first question if anyone wants to help me:

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

The two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles.

Which is NOT a justification for the proof?

Addition Property of Equality

Pythagorean Theorem

Pieces of Right Triangles Similarity Theorem

Cross Product Property

Answer 2

@andriod09
@BABYShawol184
@TheDarkKnight

can someone explain this to me?

Answer 3

Its basically asking: "which one of these will not solve this problem" I believe.

Answer 4

Do you think it would be D, "Cross product property"?

Answer 5

Okay, so I have 4 more. Do you think you can help me @andriod09

@love_jessika15 can you help me?

Answer 6

Given: In ∆ABC below,BD/BA = BE/BC .
Prove: segment DE || segment AC

The flow chart proof with missing statements and reasons proves that if a line intersects two sides of a triangle and divides these sides proportionally, the line is parallel to the third side.

Which statement and reason can be used to fill in the numbered blank spaces?

A 1. ∡BDE ≅ ∡BAC
2. Corresponding Parts of Similar Triangles

B 1. ∡BDE ≅ ∡BCA
2. Alternate Exterior Theorem

C 1. ∡BDE ≅ ∡BAC
2. Corresponding Angles Postulate

D 1. ∡BDE ≅ ∡BCA
2. Corresponding Parts of Similar Triangles
