Question

Now that you know how to prove a theorem, it’s time to do it completely on your own. Select one proof from the left column and one proof from the right column to prove. You may prove each theorem using either a two-column, paragraph, or flow chart proof. No matter the type of proof you choose, it must demonstrate a logical progression from one step to the next.
For each proof, you will need to create and submit to your instructor the initial, or given, figure: lines, segments, angles, or triangles. You may do this by hand or using technology. Select a proof to receive directions on how to cre

Answer 1

Select a proof to receive directions on how to create the initial figure using GeoGebra and a reminder as to what you are trying to prove.
I chose Triangle Proportionality Theorem and Converse of Triangle Proportionality Theorem @directrix

Answer 2

I don't know how to use this: GeoGebra.

The instructions said you could do the proof by hand.

And, can you change your theorem selections?

Answer 3

Yeah sure I can change them.... the only options I have are:
Similarity Proofs:
Triangle Proportionality Theorem
Pythagorean Theorem by Similarity

Converse Proofs:
Converse of Triangle Proportionality Theorem
Converse of Pythagorean Theorem by Similarity

Answer 4

Sorry i dont know this :/

Answer 5

So, have you chosen yet?

Answer 6

Triangle Proportionality Theorem

Answer 7

I'm thinking about the second one. I don't know the theorems by those names.
Do we have to choose the second one now?

Answer 8

Its either Triangle Proportionality Theorem or Pythagorean Theorem by Similarity

Answer 9

And Converse of Triangle Proportionality Theorem or Converse of Pythagorean Theorem by Similarity

Answer 10

We'll just go with the one you chose: Converse of Triangle Proportionality Theorem

if we have to choose right this very minute.

Answer 11

Triangle Proportionality Theorem:

Look in your book and post what the theorem says. That is where we will start.

Answer 12

Triangle Proportionality Theorem: If a line is parallel to one side of a triangle and also intersects the other two sides, the line divides the sides proportionally.

Answer 13

I do.

Answer 14

okay...

Answer 15

Figure:

Given: Triangle RST, Line PQ is parallel to line RS

To Prove: RP/PT = SQ/QT
