What is a transversal
Any line that intersects two or more parallel lines.
100
Define 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
If two angles are supplementary, and angle 1 measures 123 degrees, what does angle 2 measure?
57
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
Define corresponding angles
Two angles who are on the same sides of the transversal and are on the same sides of parallel lines
200
What is the relationship between angles 3 and 6 ?
What are Alternate Interior Angles.
200
If the complementary angle 1 measures 43 degrees, what is the measure of angle 2?
47
200
What are 3 ways we can "justify" angles?
vertical angles, supplementary angles, corresponding angles, alternate interior, alternate exterior
300
What are angles that add up to 90 degrees?
Complementary angles
300
Define an acute angle.
an angle that measures less than 90 degrees but more than 0 degrees
300
If the measure of angle 4 is 112, what is the measure of angle 6?
What is 68.
300
What is congruent mean?
same, equal
300
If the measure of angle 1 = 29, and you are trying to figure out the supplementary angle 5, what would the measure of angle 5 be?
151 degrees
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? Justify the relationship
What is 30.
400
Angles 6 and 7 are vertical angles. If the measure of angle 6 = 75 and the measure of angle 7=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
Define the triangle sum theorem
the measures of the interior angles of a triangle add up to 180 degrees
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=98°, then the measure of angle 4 is: Justify the relationship as well
angle 4= 98 degrees
