Two angles that add up to be 90 degrees
What are complimentary angles?
Find the missing angle

What is 15 degrees?
The angle relationship being displayed is ______

What is Vertical?
A triangle has side lengths 12 in, 25 in and 13 in. SHOW why it does or why it does not form a triangle?
NO. 12 + 13 = 25 which is NOT greater than 25.
Two angles that add up to be 180 degrees
What are Supplementary angles?
Find the missing angle
What is 103 degrees?
Angle Y is _______
What is 76 degrees?
A triangle has angles that measure 30o, 40o, and 110o and side lengths 14cm, 28cm, and 40cm. Classify the triangle by angles AND by sides.
The interior angles of a triangle must always add up to be _______
What is 180 degrees?
Solve for x

What is 30 degrees?
Angle X is _______
What is 104 degrees?
A triangle has angle measures of 30 degrees, 42 degrees. What is the measure of the third angle?
108 degrees
What kind of angles only share a vertex and are congruent?
Vertical
Solve for x and the missing angle

What is x=66 and angle=132 degrees
Angle C is _______

What is 50 degrees?
A triangle has angles that measure x + 5 degrees, x - 11 degrees, and 20 degrees. Solve for x.
x + 5 + x - 11 + 20 = 180
2x + 14 = 180
2x = 166
x = 83
If the first 2 interior angles of a triangle are 98 degrees and 47 degrees, what is the measure of the third?
What is 35 degrees?
What is the value of the larger angle?
What is 65 degrees?
This triangle classified by angle and side length is _______ and _________ 
What is an obtuse and scalene triangle?
An equiangular triangle has an angle that measures x + 3 degrees. What is the value of x?
x + 3 + x + 3 + x + 3 = 180
3x + 9 = 180
3x = 171
x = 57
