In case you are looking for the questions that went with our city designing task from class today, the link to the document can be found below.
If you are wanting to check your answers to the homework sheet from last night on interior and exterior angles, you can click on the appropriate answer key below. This homework can be used in addition to everything in the Unit 1 Review Post to study for your test tomorrow.
We are moving along! We are entering the world of triangles. Here is a video to help you with these concepts. In case you want to practice your angle vocab before the quiz today, here is the link to the matching game from yesterday. Remember: drag the terms over to the picture you think they go with.
Click here for the game. ![]() Today we looked at the special angle relationships that are created when parallel lines are cut by a transversal. First, let's define a few terms. Parallel lines are lines that never intersect each other. They go on forever and never touch. Transversals are lines that cut through or intersect the parallel lines at distinct points. In the picture below, the red line is the transversal and the blue lines are parallel. The numbered angles are created by the intersection of the transversal with the parallel lines. This section is very vocabulary intensive. You will need to know the following vocabulary words: Vertical Angles (equal to each other) Alternate Interior Angles (equal to each other) Alternate Exterior Angles (equal to each other) Same Side Interior Angles (supplementary) Same Side Exterior Angles (supplementary) Corresponding Angles (equal to each other) Complementary Angles (add up to 90 degrees-form a right angle) Supplementary Angles (add up to 180 degrees-form a straight line) Here are some examples from the picture above.
Vertical angle pairs: 1 and 3, 2 and 4, 5 and 7, 6 and 8 Alternate Interior Angles: 4 and 6, 3 and 5 Alternate Exterior Angles: 1 and 7, 2 and 8 Same Side Interior Angles: 4 and 5, 3 and 6 Same Side Exterior Angles: 1 and 8, 2 and 7 Corresponding Angles: 1 and 5, 2 and 6, 4 and 8, 3 and 7 Supplementary Angles: 1 and 2, 2 and 3, 3 and 4, 1 and 4, 5 and 6, 6 and 7, you get the point. |
