Yes, all three of their angles are congruent
200
What is the supplementary angle to 87.1 degrees?
92.9 degrees
Remember supplementary angles add up to 180 degrees.
200
What is the measure of angles 1 and 2?
< 1 = 18 degrees
< 2 = 162 degrees
200
What angle pair are angles 3 and 5?
Same Side Interior
200
Solve for angle x
x = 70 degrees
The sum of the two interior angles always equals the exterior angle
200
Are the following similar? Why?
No, not every angle is congruent
300
True or False:
Vertical Angles are always congruent.
True
Vertical angles always equal the same measurement, congruent just means equal

What is the measure of angle 5 and angle 1?
< 5 = 154 degrees
< 1 = 26 degrees
300
What are the angle pair names that a transversal creates.
There's 6 of them!
Vertical, Corresponding, Alternate Interior, Alternate Exterior, Same Side Interior, and Same Side Exterior

Solve for x.
x = 5
13x+ 16x + 7x = 180 Combine Like Terms, solve for x

True or False:
Two shapes are similar when they have the exact same size, but not the same shape.
True, the angles all need to be the same. When we dilate shapes they stay similar to the Pre-image

If <x, <y, and <z are all supplementary to each other, find the measure of <z
<x = 53.1
<y = 32.7
<z = ?
< z = 93.2 degrees
Remember supplementary angles add up to 180 degrees. So <x + <y + <z = 180
400
Solve for x:
x = 19
400
If <3 and <4 are Alternate Exterior Angles, what is the measure of <4 if <3 equals 134.8 degrees?
<4 equals 134.8 degrees
Remember Alternate Exterior angles are congruent, making <3 and <4 equal to one another

Solve for h. Separate the two triangles to help you
h = 2/3
500
If <h and <g are complementary to each other, what would <h equal if <g is 69.7 degrees?
<h equals 20.3 degrees
Remember complementary angles add up to 90 degrees
500
What is the measure of the two angles?
122 degrees
Set them both equal to each other, then solve for x

Name three pairs of corresponding angles:
<1 and <4
<2 and <6
<3 and <7
154 degrees and <5

If Triangle ABC had the following angles, find the measure of angle C
< A = 13.6 degrees
< B = 109.2 degrees
< C =?
< C = 57.2 degrees
