Missing Angle Measurements
100
Two angles that add up to 90 degrees.
What are complementary angles?
100
Two angles that add up to 180 degrees (a straight line)
What are supplementary angles?
100
This angle and angle 5 are supplementary.
What is angle 1 or angle 6
100
Vertical angles: angle 3 and _____
What is angle 8
100
If angle 3 = 130 degrees, angle 8 = ______ because ____________.
What is 130 degrees because they are vertical angles. (Vertical angles are congruent)
200
Angles with the same measurement.
What is congruent?
200
All of the angles found between (inside of) the parallel lines.
What are interior angles?
200
Corresponding angles: Angle 5 and ______
What is angle 7
200
Interior angles: Angle 2, ______, _____, _____
What are Angles 3, 6, and 7
200
If Angle 8 = 119 degrees, angle 4 = _____ because ______.
What is 61 degrees because they are supplementary angles. (180 - 119 = 61)
300
Lines that will never intersect and have the same distance between each other.
What are parallel lines?
300
Lines that intersect to form right angles.
What are perpendicular lines?
300
Identify the transversal
What is line Z
300
How many angle measurements are needed to find the all the angle measurements created by a transversal intersecting 2 parallel lines?
What is 1
300
If angle 4 = 37 degrees, angle 5 = ____ because _____.
What is 37 degrees because they are alternate exterior angles. (Alternate Exterior Angles are congruent)
400
Any line that intersects two or more lines.
What is a transversal?
400
Angles found outside of the parallel lines and on opposite sides of the transversal.
What are alternate exterior angles?
400
True or false: angles 3 and 7 are congruent.
What is False - they are supplementary.
400
True or false: Angles 1 and 6 are congruent because they are corresponding angles.
What is False - they are congruent because they are vertical angles.
400
If angle 6 = 145 degrees then angle 7 = _____ because ______.
What is 35 degrees because they are same side interior angles. (Same side interior angles are supplementary so 180 - 145 = 35)
