If angle 1 has a measure of 135^o, then m∠6 =

• 90^o

• 135^o

• 45^o

• 65^o

Answer explanation

If angle 1 measures 135° then angle 5 measures 135° because they are corresponding angles. Angle 5 and 6 form a linear pair and are supplementary, so you can subtract 135 from 180 to find the measure of angle 6.

If m∠6 = 50^o then m∠4 =

• 50^o

• 90^o

• 130^o

• 360^o

Answer explanation

Angle 6 and 4 are SSIA and are supplementary. 50 + x = 180
