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
On a transversal, a pair of adjacent angles formed on a straight line that add up 180
What is linear pair
100
If a transversal cuts two parallel lines, how many angles are formed?
What are 8
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
angles that are the same size
What is congruent angles
200
What is the first step in identifying in angle a relationship on a transversal cut?
Asking oneself are my two angles on the same side or alternating (opposite) sides of the transversal.
300
What are Corresponding Angles.
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
300
Linear Pair Angles
A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.
300
If the measure of angle 4 is 112, what is the measure of angle 6?
What is 68. (same-side interior angles)
300
Given two supplementary angles, if one angle is 75 what is the measure of the other angle?
105
300
If the measure of angle 1 is 4x-6 and the measure of angle 5 is 122, what is the value of x?
32
400
What are 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?
What is 30.
400
if the measure of 2 vertical angles are 75 and 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
Same-side interior angles
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
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
Given that a || m, measure of angle 5 is 98°, then the measures of angles 3 and 4 are:
What is angle 3 is 82 degrees and angle 4 is 98 degrees
500
If the measure of angle 4 is 5x+3 and the measure of angle 6 is 8x-5, then find the value of x.
x=14
