Find the measure of the missing angles.

yº

Angle a and the 70° angle are opposite angles so they are equal.Angle a = 70°

Angle b and the 135° angle are supplementary so they add up to 180°.135° + b = 180°b = 180° - 135°b = 45°

We now know two angles in a triangle. These two angles along with angle c add up to 180°.c + 70° + 45° = 180°c = 180° - 115°c = 65°

Angles d and b are alternate angles and, since the two lines are parallel, they are equal.d = 45°

Angle e and the 70° angle are corresponding angles and, since the two lines are parallel, they are equal.e = 70°

Angle f and angle e are supplementary. They add up to 180°.70° + f = 180°f = 180° - 70°f = 110°

Step-by-step explanation:

The missing angles will not always be labeled a, b, c, d, etc. so the sequence in which to find angles might not be obvious. Sometimes it is best to just start finding whatever angles you can and keep going until all the ones that are required are found.
