do u know what a linear pair is?

3. HaileyroX!

The two supplementary adjacent angles formed by two intersecting lines

4. Nikhil619

@HaileyroX! yeah..gud so use that!

5. HaileyroX!

I thought all the angles would have to be 280 all together but it would be too much! so maybe it has to go to 560?

6. AravindG

3 and 4 form a linear pair.Use that idea to get 4

7. HaileyroX!

i dont think i understand linear pair that well

8. AravindG

linear pair is any two angles that add upto 180 degree

10. AravindG

take a look at the diagram, her A and B form a linear pair so A=180-B B=180-A And A+B=180
