8th Grade: Module 4 Lesson 3 ON YOUR OWN

The picture shows a bridge between parallel river banks.

What angle does the driver's right turn make with the river after crossing the bridge to continue on Northbridge Road?

Solve for x:

Which two angles have the same measure?

Lines m and n are parallel.

Find the following angle pairs in the diagram.

2. 1. Corresponding angles:​ (a)  

3. 2. Same-side exterior:​ (b)  

4. 3. Alternate interior:​ (c)  

5. 4. Same-side interior:​ (d)   ​

• 2 and 4
• 3 and 4
• 1 and 5
• 3 and 5
• none

Two angles are same side interior angles.

The measures of the angles are represented by the expressions 7x + 18 and 10x + 9.

What are the two angle measures?
