angles in parallel lines

how do you do angles in parallel lines?
so look up

"alternate angles"

"corresponding angles"

"opposite angles"
And

"Allied angles" (aka co-interior)

"Angles on a straight line"

"Angles in a triangle"

"Base angles in an isosceles triangle"

As the bear suggests, learn all the rules. Then when faced with a problem don't worry at first about what angle you are asked to look for, apply all of the rules you can remember to work out angles in the diagram until the answer falls off the page.
