Angles on parallel lines

Step 1 — Name the pairThe given angle and the one we want are corresponding (F) angles.

Step 2 — Pick the ruleCorresponding angles are equal.

Step 3 — Work it outx = 62°

Your turn — first, what kind of pair is it?

…and what is x? degrees

The lines are parallel, so the rules apply. Decide the pair first (F = corresponding = equal, Z = alternate = equal, C = co-interior = add to 180°), then find x.
