  1. Katie earns a commission at her job. She earns 5% on the first $10,000 in sales and 8% on anything over $10,000. What is her paycheck if her sales reached $14,000 this month? Bellwork

  2. Timed Skill Drill Homework Review Daily Activities!

  3. Did You Realize? By: Mrs. Yow Pre-Algebra obj. 7.3.a, 7.3.b

  4. Why learn about Angles? • Angles of course are a very important concept in geometry. • However, you may not have realized that angles impact our lives in more ways than • we think. Let me show you some examples….

  5. Did you realize. . . Angles are a part of your favorite sport? There is an angle tackle in football! Quarterbacks pass at an angle to the receiver!

  6. Did you realize. . . Outfielders run at an angle to catch the ball?

  7. Did your realize . . . Drivers and Pilots use angles? • When parking a car a driver uses the concept of angles to park in a particular space. • A pilot maneuvers an airplane using a variety of angles to fly and land.

  8. Chefs chop at an angle?

  9. X-Gamers spin their bikes at an angle. X-Games

  10. A contractor uses angles to build a house, a school, or any structure. • A nurse adjusts a bed to create an angle that is comfortable for a patient. • Umbrella’s can be tilted at an angle in order to stop rain, snow, or provide shade. Here are some more examples.

  11. A transversal line intersects two or more lines in a plane. It is helpful to us when the intersected lines are parallel (like the ones pictured)! Angles are formed by intersecting lines…..TRANSVERSAL LINES….also

  12. A transversal is a line that crosses 2 parallel lines. (8 angles are formed by a transversal) 1 2 The red line is the transversal! 4 3 5 6 8 7 What is a Transversal?

  13. Find the Transversal.

  14. Find the Transversal.

  15. All of these have transversals. Black Rose Gibson Les Paul Gibson Flying V

  16. Vertical • Corresponding • Alternate INTERIOR • Alternate EXTERIOR Types of Angles formed:

  17. 1 2 4 3 5 6 8 7 Vertical Angles Share a vertex

  18. 1 2 4 3 5 6 8 7 Corresponding Angles

  19. 1 2 4 3 5 6 8 7 Alternate Interior Angles Different Sides of Transversal/ Inside of parallel lines

  20. 1 2 4 3 5 6 8 7 Alternate Exterior Angles Different Sides of Transversal/ Outside of parallel lines

  21. When are corresponding, alternate interior, alternate exterior, etc. angles NOT be equal to each other? Closure
