What is the measure of angle MN?
180
What relationship is shown below:
Complementary Angles
Solve for x algebraically. Find the measure of each angle including angle 1.
6x-19 = 3x + 32 (Vertical Angles are congruent)
x = 17
6x-19 = 83 degrees
3x+32= 83 degrees
angle 1 = 180-83 = 97 degrees
What angle pair is formed by 3 and 6? If angle 3 is 120, what is the measure of angle 6?
Alternate interior, 120

Define angle 1 as acute, obtuse, straight, or right.
Acute
Define the angle relationship
68 + 82 = 90
Solve for the missing angles and state how you know.
angle 1 = 47 (Vertical to given angle 47 degrees)
angle 2 = 43 (Complementary to angle 1)
angle 3 = 90 (Vertical to given right angle)
angle 4 = 43 (Complementary to given angle 47 degrees or vertical to angle 2)
What kind of angle pair is formed by angles 4 and 8? If angle 4 is 75, what is the measure of angle 8?
Corresponding, 75

Answers Vary -- Must have right angle box
Find the measure of x and y.
Be prepared to explain how you know.
x = 132 because it is supplementary to given angle (48 degrees) 180-48=32
y = 132 because it is vertical to angle x OR also supplementary to given angle (48 degrees)
angle 1 = 63
angle 2 = 117
angle 3 = 63

Find the value of x algebraically.
Be prepared to explain how you know.
x+10+50 = 90
x = 30
The angles form a right angle.
OR
90+x+10+50=180
Straight line angles.
Solve for x algebraically. What reason supports your equation?
x+x+82=180
x = 49
Straight Line Angles
Name the angle pair and find the value of x algebraically.
Vertical Angles, x=14

Find the value of x
x = 11
Find the value of x and y algebraically. Give reasons to support your equation(s).
3x+6=y (Vertical Angles)
x-10+3x+6+x-11=180 (Straight Line Angles)
x= 39
3(39)+6 = 123
So, y = 123
Find the value of x and y. State how you know.
3x+19=4x+14 (Corresponding Angles)
x=5
4(5)+14=34
y=180-34=146 (Consecutive Interior to 4x+14 OR Supplementary to 3x+19)
