------------------------------------------------------------------------------------------------------------------------

## 7) The orange angle multiplied by six equals the value of the orange angle plus the pink angle. What is the measure of the pink angle?

------------------------------------------------------------------------------------------------------------------------

## 8) What construction is this the start of? What would be the next step in this construction?

------------------------------------------------------------------------------------------------------------------------

## 9) The measure of angle x is 60 degrees. What is the measure of angle 1 and how do you know that?

------------------------------------------------------------------------------------------------------------------------

## 10) What is the relationship between the two blue lines?

------------------------------------------------------------------------------------------------------------------------

1) x= 50 degrees and y= 130 degrees

2) 120 degrees

3) There is no relationship (they are NOT corresponding)

4) AAS (Angle Angle Side)

5) Sq. rt of 5 or 2.236

6) Blue line: m= -2/3. Green line: m= 3/2

7) Measure of pink angle= 360 degrees

8) This is an angle bisector construction. Bisect the brown line

9) Angle 1= 160 degrees. x is supplementary to angle 4. Angle 4 is an alternate exterior angle to angle 1.

10) The lines are co-planar or parallel.
