If two parallel lines are cut by a ____________, there will be 8 angles
Transversal.
300
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
What are Corresponding Angles.
300
Alternate angles
See white boards

If angle 2 is 88 degrees, what does angle 6 equal. explain
88 degrees, corresponding angles
400
What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
400
Corresponding angles.
See whiteboards.
400
What is the relationship between angles 5 and 8?
Vertically opposite angles.
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 6? Explain!
30 Corresponding angles
400
what does angle 3 equal - give a reason.
45 degrees - corresponding angles
500
What are Alternate Interior Angles?
When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal and congruent.
500
Angles around a point.
See whiteboards
500
If the measure of angle 2 is 37 degrees, what is the measure of angle 7? Explain your answer.
37. Using Vertically opposite then corresponding angles.
500
Given that angle 2 is 82 degrees, what does is the measure of angle 3, then what is the measure of angle 4 ?
Angle 3 =82 degrees, vertically opposite
and angle 4= 98 degrees, supplementary
500
If angle 1 is equal to 95, what is angle 7 equal to? Explain
95 degrees - vertically opposite then corresponding.
