How many angles do you see that were created?

What type of angles did he say these were?

Then the other obtuse "green" angle would be​ (a)   .

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

What is the missing angle measure?

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

What would all the orange angle measures equal?

If the purple angle measures were 42º, then the orange angle measures would be ​ (a)   .

Categorize the angles as either congruent or supplementary to ∠7.
