A green angle and a blue angle form a ​ (a)   which makes the angles ​ (b)   .

• linear pair

• supplementary

• complementary

• right angle

What is the missing angle measure?

• 122º

• 58ª

We know the purple angle measure that is directly across from the 30º angle is ​ (a)   because those angles are ​ (b)   .

• 30º

• vertical

• 150º

• 90º

• adjacent

• corresponding

What would all the orange angle measures equal?

• 150º

• 30º
