100
What are Vertical Angles?
Angles across from each other or opposite AND congruent(the same).
100
Define complementary angles.
Two angles that add up to 90o.
100
Define Supplementary Angles.
Two angles that add up to 180.
100
Define congruent.
Equal, or the same.
200

Obtuse Angle
200
What is the measurement of Angle b?
47o
200
Give an example of two complementary angles.
Any two numbers that add up to 90.
200
(T or F) This is an example of Supplementary Angles.
True.
200
Define angle.
Two lines or rays with the same endpoint.
300
How would you describe a 45o angle?
Acute
300
Angles a and c are vertical angles. (T or F)
True.
300
True or false (If false explain) This is an example of complementary angles.
False. These are supplementary or add up to 180, not 90.
False. Complementary angles add up to 90, not 180.
300
Give an example of Supplementary Angles.
Any two angles that add up to 180.
300

Lines l and m.
400
These are examples of Obtuse Angles. (T or F)
True
400

28.
400
If angle 1 is 75o then what is angle 2?
105.
400
Give an example of vertical angles.
Varies.
500
Agree or Disagree. Explain. The first image is a Right Angle.
Disagree. Right Angles are 90o.
500
If Angle b is 47. What is Angle a & c?
33 each!
500
Agree or Disagree. Explain. This is not an example of complementary angles.
Disagree. Both angles add up to 90 so this IS an example of complementary angles.
500
133
500
T or F (explain). There aren't any perpendicular lines because none of the intersecting lines for a right angle.
True. Perpendicular lines must form a right angle.
