What is Similarity Postulate?
The above answers shows that:
5. Reflexive Property
6. AA Similarity Postulate
7. Polygon Similarity Postulate
8. Cross Multiply and Simplify
9. All right angles are Congruent
10. Reflexive Property
11. AA similarity Postulate
To prove the above:
Note that the full proof of the Pythagorean theorem is that:
We are given: Δ ABC as a right triangle, with a right angle at ∠C.
Then the Prove: A²+B² =C²
Therefore, If you follow the theories above, you will see that the answers given are correct.
