What You Need To Know...
Identify and use the relationships between special pairs of angles formed by parallel lines and transversals.
- The benchmark will be assessed using MC (Multiple Choice) and FR (Fill in Response) items.
- Items may have multiple sets of parallel lines.
Example One
In the figure below,
is parallel to .
Which of the following statements about the figure must be true?
Example Two
Highlands Park is located between two parallel streets, Walker Street and James Avenue. The park faces Walker Street and is bordered by two brick walls that intersect James Avenue at Point C, as shown below.
What is the measure, in degrees, of ∠ACB, the angle formed by the park's two brick walls?
