• greater than
• less than 
• equal to

Multiple Choice

Does a triangle with these side lengths exist?

20, 10, 9

• Yes, only one

• No

• Yes, many

Multiple Choice

• Only 1 unique triangle

• multiple triangles

• no triangles

Multiple Choice

What is an example of a pair of complementary angles?

• 13° and 45°
• 10° and 170°
• 81° and 9°
• 90° and 3°

Multiple Choice

If m∠1 = 30°, then m∠3 = 

• 30°
• 60°

• undetermined

Multiple Choice

Use the right angle on the previous slide to answer the following questions.

What is the solution for x?

What is the measure for the two angles shown?

• x = 60

• x = 30

• x = 90

• angles = 30 & 60 degrees

• angles = 20 & 70 degrees

Once we solve for x, we can now substitute x in to find out the measure for each angle.

2(61) + 3 = 125
(61) - 6 = 55
The angle to the left is 125 degrees 
The angle to the right is 55 degrees

Added together they equal 180 degrees

We know that these two angles are supplementary angles because added together they will equal 180 degrees (a straight line). To solve this equation, add both of these expressions together and set them equal to 180.
 $2x+3+x-6=180$  

 $3x\ -3=180$  
 $3x=183$  
 $x=61$  

Multiple Choice

<ABC and <FAD are supplementary angles, and <ABC = 90 degrees, what is the measure for <FAD?

• 180

• 90

• 100

• 0

SUPPLEMENTARY

two angles are supplementary angles when adding their measure of degree equals 180.

COMPLEMENTARY

two angles are complimentary when adding their measure of degree together equals 90.
