Have one Side be the statement and the other side be the reason.

3. grayp

statements and reasons

4. matricked

intriangle ABC and triangle ADE 1) <BAC =<DAE (reason ---- common to both) 2) <ABC =< ADE (reason corresponding angles as DE||BC and AB is the transversal) hence triangle ABC and ADE are similar

5. grayp

nice work.

6. matricked

i hope its clear to u me little lazy in drawing tables and other stuffs

7. grayp

Your answering a little different then what my teacher does. Can't you answer it with a similarity postulate?

8. mathstudent55

Statements | Reasons --------------------------------------------------------------- 1. BC || DE | 1. Given 2. <A is congr to <A | 2. Congruence of angles is reflexive 3. <ABC is congr to <ADE | 3. || lines cut by tranversal, corrsesp <s congr. 4. triangle ABC ~ triangle ADE | 4. AA similarity

9. grayp

Much better.

10. grayp

is the greater sign mean the triangle?

11. mathstudent55

This is basically what matricked did. It just looks more formal.

12. grayp

Thanks both of you then. That is all

13. mathstudent55

No, < means angle. For triangle I actually spelled out triangle.

14. grayp

oh ok.
