Introduction
Recall that city roads are great examples of lines that are cut by a transversal.
In this lesson you will take the angle relationships and place the buildings and red lights in the correct place. You may need to review how to take a screen shot to submit your work.
Following successful completion of this lesson, students will be able to...
- Apply angle relationships in a real-world situation
Essential Questions
- How can I prove that two lines are parallel or perpendicular using angle measurements?
- How can I use theorems and postulates about lines and angles to solve problems?
Enduring Understandings
- Perpendicular lines can be proven by the relationship of their slopes.
- If we know the measure of one angle formed when a pair of parallel lines is cut by a transversal, then we can find the measures of the other angles.
- You can use the measures of angles to prove that lines are parallel.
- If we know the measure of one angle formed when a pair of parallel lines is cut by a transversal, then we can find the measures of the other angles.
- You can use theorems and postulates about lines and angles to find unkonwn measurements.
