ANGLE RELATIONSHIPSLearning Goals:

❏ I can recognize when an angle measures 90o, 180o, or 360o.❏ I can find unknown angle measures by reasoning about complementary and supplementary angles.❏ I can explain what vertical angles are in my own words.❏ I can reason to find unknown angle measures.❏ I can write an equation to represent a relationship between angle measures and solve the equation

to find unknown angle measures.

Desmos Lines and AnglesExplore the relationship among angles formed by intersecting lines. Please complete the entire activity, sharing your reasoning along the way!

FRIDAY- ShareCreate and submit Flipgrid video explaining how to solve for angle b to show all you know about different types of angles! Access the image in below or using this link if you’d like to zoom-in or print.

Tips: On Flipgrid, you can stop and resume recording as you go. You may also create a video using a different app and upload it to our grid (Directions to upload are here!). If you’d prefer to submit a picture with detailed work or something else that explains your reasoning, that’s fine!

FRIDAY- ReflectIn this box, complete the following lists based on what you learned about in this hyperdoc.
