​Did you get it wrong?

​since < 1 + < 2 + < 3 = 180 just plug in what you know.

​

​2x + 1 + 5x + 5 + 90 = 180

​now combine like terms since they are on one side.

​7x + 96 = 180. Now solve like normal

​ - 96 -96

​7x = 84

​ /7 /7

​ x = 12

Multiple Choice

Solve for x.

• 44^o

• ^-14o

• -7^o

• 63^o

Multiple Choice

Which of the following angles can you add together to equal angle d? 

• Angle a and Angle b
• Angle b and Angle c
• Angle a and Angle c
• Angle a and Angle b and Angle c

Multiple Choice

What is the measure of angle b?

• 36^o
• 56^o
• 63^o
• 117^o

Multiple Choice

What is the measure of angle x?

• 45
• 60
• 65
• 75

Multiple Choice

Solve for x.

• A

• B

• C

• D

​Did you get it wrong?

​Set up the formula

Exterior = remote + remote

​9x + 7 = 30 + 6x + 13

​Combine like terms on same side

​9x + 7 = 6x + 43 now move variables

​-6x -6x

​3x + 7 = 43 now move constants

​ -7 -7

​3x = 36 finally divide by 3

​ /3 /3

​ x = 12

Multiple Choice

Solve for x.

• A

• B

• C

• D

Multiple Choice

Solve for x.

• A

• B

• C

• D

​Angle Angle Similarity

​As long as 2 angles of different triangles are CONGRUENT, the 3rd angle MUST be congruent also!

​

This means that triangles are SIMILAR if they have 2 congruent angles!

​

​Remember to find the 3rd angle just to be sure!!!

Multiple Choice

Are the triangles similar?

• Yes
• No

​Transversals p1

​Parallel lines cut by another line (transversal) creates 8 angles.

​The key is that there are really on TWO types of angles

​

Acute: 1, 4, 5, 8

​

Obtuse: 2, 3, 6, 7

​

​

​Transversals p2

​The connections are simple, if they are the SAME type of angle they are EQUAL to each other

​A = A ex: < 1 = < 4

O = O ex: < 2 = < 6

​

​If they are DIFFERENT types of angles they ADD UP TO 180!

​A + O = 180

​ex: < 1 + < 7 = 180

Multiple Choice

WHAT IS THE VALUE OF X?

• 16
• 11.4
• 0 
• -16

Multiple Choice

WHICH IS THE CORRECT EQUATION TO SOLVE FOR X?

• 16X+180 = 90

• 12X - 29 = 4X +1

• 12X - 29 + 4X +1=90

• 12X - 29 + 4X +1=180
