In this lesson, we will learn how to investigate the relationship between angles in intersecting lines and find the measure of unknown angles.
Students will be able to
Q1:
If two angles are vertically opposite, are they equal in measure?
Q2:
Given that lines ⃖⃗𝐴𝐵 and ⃖⃗𝐶𝐷 intersect at 𝑂, find 𝑚∠𝐴𝑂𝐶.
Q3:
In the figure, lines ⃖⃗𝐴𝐵 and ⃖⃗𝐶𝐷 intersect at 𝐿. What is 𝑚∠𝐴𝐿𝐷?
