## annipuppi one year ago Find the values of the variables in the parallelogram.

2. myininaya

Use the fact the triangles are congruent.

3. annipuppi

Sorry I went to eat dinner. Can you explain some more @myininaya

4. jdoe0001

means, the corresponding sides and angles in each will equal each other

5. myininaya

Congruent means you can find all 3 angle and all 3 side measurements in both triangles.

6. jdoe0001

the really long side with the other really long side equals to each other the shorter one with the other and the last one with the last one of the other

7. jdoe0001

same goes for the angles

8. annipuppi

So x=109 y=48 and x=48? How do you know the triangles are congruent?

9. jdoe0001

so just mix and match =)

11. jdoe0001

x = 109?

12. myininaya

Because of the SSS rule.

13. annipuppi

i meant z=109.. wait so x doesn't equal 48 then... how do I find x?

14. jdoe0001

recall that all internal angles SUM UP to 180

15. myininaya

You can also use the fact the angles in a a triangle add up to be 180 degrees.

16. annipuppi

okay so z=109, x=33, and y=38?
