Applying the properties of angles created when parallel lines are cut by a transversal

Find the value of x.

Find the missing angle measure

• 70^o

• 110^o

Find y.

• 50°
• 130°
• 180°

• 140°

If ∠2 is supplementary to ∠3, then line a is parallel to line _.

Find the measure of the indicated angle.

• $70\degree$

• $135\degree$

• $100\degree$

• $110\degree$

If angle 2 is 70 degrees what is the measure of angle 7?

• 70

• 110

• 180

• 20

Solve for x:

What is the value for angle b?

• 50^o

• 65^o

• 115^o

• 130^o

 $Given:\ \angle14\ and\ \angle15\ are\ \ \ Supplementary.$ 

Which lines are parallel?

•  $r\parallel s$  

•  $t\parallel u$  

•  $r\parallel s\ and\ t\parallel u$  

• No parallel lines

Answer explanation

A linear pair is always supplementary but NEVER prove that lines are parallel.

What is the value of angle 1 if angle 2 is 60?

• 180

• 120

• 60
