Angle Relationships Part 2
100
What is a transversal?
Any line that intersects two or more parallel lines.
100
Parallel lines
Straight lines that never intersect
100
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle?
What is 42
100

What are same side interior angles?

angles that lie on the same side of the transversal, inside the parallel lines

100
If angle 1 is 55 degrees, draw and find ALL ANGLES.

Angle 1, 4, 5, and 8 are 55 degrees.


Angle 2, 3, 6, and 7 are 125 degrees.

200
What are supplementary angles?
Two angles whose measures add up to 180 degrees
200
Complementary Angles
Two angles whose measures add up to 90
200
What is the relationship between angles 3 and 6 ?
What are Alternate Interior Angles.
200

What are same side exterior angles?

Angles that lie on the same side of the transversal, between the parallel lines.

200

If angle 1 is 2x and angle 4 is 90 - x, find the value of x.

x = 30
300
What are angles that add up to 90 degrees?
Complementary angles
300
Vertical Angles
Angles that are straight across on a pair of intersecting lines.
300
If the measure of angle 4 is 112, what is the measure of angle 6?
What is 68. (same-side interior angles)
300

Tell me something we know about the relationship of alternate exterior angles.

They are congruent.

300
If the measure of angle 1 = 4x-6 and the measure of angle 5 =122, what is the value of x?
 x=32
400

[Daily Double!] Tell me two things about vertical angles.

Congruent angles formed by two intersecting lines. These angles are located across from each other.

400
Alternate Exterior Angles
If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.
400
What is the relationship between angles 5 and 8?
What are Vertical Angles.
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 6?
30 degrees
400
Angles 6 and 7 are vertical angles. If the measure of angle 6 is 75 and the measure of angle 7 is 3x, what is the value of x?
x=25
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.
500

Corresponding Angles

Two angles on the same side of the transversal and on the same side of parallel lines

500
If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?
What is 37 and Alternate Exterior.
500
