You know 2 angles are complementary when they are _____ degrees.
90 degrees
100
You know two angles are supplementary when they add up to ______ degrees
180 degrees
100
How do you know if an angle is vertical?
If they are opposite each other and are the same degree
100
How many degrees is a right angle?
90
200
Draw an example of 2 parallel lines
up and down, across
200
True or False: Complementary angles can not be two separate angles
False, as long as they add up to 90 degrees they can be two separate angles
200
Draw a picture of a supplementary angle.
As long as they add up to 180 degrees they are correct
200
What would you have to subtract 70 by to find the adjacent angle (angle next to it that shares a common side and vertex)
180
200
How do I know if it is a perpendicular line?
Two lines that intersect and form a right angle
300
What is the definition of a parallel line?
Two lines that never intersect one another
300
What is the complement of a 75 degree angle?
15 degrees
300
True or False: Supplementary angles all must be linear angles (form a straight line)
False because the angles don't have to be connected to be supplementary, they can be pairs of angles next to each other.
300
If two angles are vertical and 1 angle is 25 degrees, what is the vertical angle opposite that angle ?
25 degrees because vertical angles have the same degree measure for the opposite angle.
300
True or False: Any lines that intersect are right angles
False
400
True or False: Parallel lines are at a right angle to one another?
False
400
What is the complement of m<1 CED if m
65 degrees because 65+25= 90
400
What is the supplement of a 25 degree angle? Show your work.
155 degrees because 155+25= 180
400
use your protractor to draw vertical angles with a measure of 30 degrees and one measure of 150 degrees.
check measures.
400
True or False: All perpendicular lines are right angles
True
500
Draw an example of 2 parallel lines and a non example of a parallel line and explain why it is a non example.
Drawing will show 2 lines that will not cross and second drawing will show 2 lines that do cross or look like they will cross.
500
What is the complement of my second angle if 1 of my angles is 180?
Trick question! These would not be complementary because they would not add up to 90 degrees because you can't have a negative angle.
500
Draw an example and a non example of supplementary angles.
any two angles adding up to 180 would be supplementary, anything not would be a non example.
500
Draw using a protractor: angles that are vertical angles and label.
Must be vertical
500
What is the difference when I say "two lines that intersect" vs. "two lines that are perpendicular"?
Intersecting lines could intersect to form any angle measure. perpendicular has to form a 90 degree angle when they intersect.
