  4. Please get out your agenda and record tonight’s homework. • 1. “Geometry –Review for Pretest” #27-32. • 2. BREAKING NEWS! • Pretest has been moved to Wednesday, September 17th. Homework

  5. 1. Identify and/or recognize: points, lines, planes, segments, rays. 2. Identify special pairs of angles. 3. Find the surface area and volume of a prism. Learning Objectives

  6. Warm Up

  7. Line: • A series of points that extends in 2 opposite directions without end • Can name a line by any two points on the line with a line above it, or by a single lower case letter. Vocabulary In Geometry, it is important to use the correct notations! A B

  8. Segment: part of the line consisting of 2 endpoints and all the points between them How you name a segment: Use the 2 endpoints with a straight line above. Read “segment AB” or “segment BA” Vocabulary - Segments B A

  9. Ray: part of a line consisting of one endpoint and all the points of the line on one side of the endpoint How you name a ray: Endpoint must be first, then any other point on the ray; write an arrow pointing to the right above Read “Ray AB” or “Ray AC”. DO NOT write Ray BA or Ray CA. Must name endpoint first!! Vocabulary - Rays A B

  10. A flat surface that has no thickness Contains many lines Extends w/o end in the direction of all its lines Named by a single capital letter OR by AT LEAST 3 POINTS NOT ON THE SAME LINE Vocabulary - Planes Plane ABC

  11. Planes that do not intersect Example: 1. Name a plane parallel to plane EGH. Answer: Plane _____ Parallel Planes // D E A F C G B H

  12. 1. Name 2 parallel segments. Parallel Segments // D A C B

  13. Use the following image to answer the question. Name a line. 2. Name a segment. Name a ray.

  14. What is an angle? • Formed by 2 rays with the same endpoint • How do you name an angle? 3 ways. Naming an Angle 1 NOTE: the middle letter is the vertex

  15. Complementary 2 angles that add up to 90˚ Supplementary: 2 angles that add up to 180˚ All straight angles form a line, therefore measure 180˚ Vocabulary Angles:

  16. Triangles:

  17. A question will appear on the ENOBoard. Write your answer on the whiteboard and raise it up. Let’s Practice!

  18. 1. Classify the Triangle (by angles)

  19. 2. Classify the triangle (by sides)

  20. 3. Solve for the missing side.

  21. (-2, -4) 4. Name the Quadrant.

  22. 5. Find the measure of the missing angle.

  23. Non-adjacent Lie on opposite sides of the transversal in between the 2 lines it intersects Remember: interior means inside the parallel lines. These angles are congruent. Alternate Interior Angles

  24. Lie outside the 2 parallel lines on opposite sides of the transversal. These angles are congruent. Alternate Exterior Angles

  25. Lie on the same side of the transversal In corresponding (same) positions Corresponding angles are congruent. Corresponding Angles

  26. Same Side _____________ Same Side Interior Same Side Exterior Angles are supplementary. (add up to ______). • Angles are supplementary (add up to ______).

  27. Vertical Angles • Vertical angles share the same vertex. • Vertical angles are congruent.

  28. Surface Area In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same. Example: Find the surface area of the box.

  29. The amount of space occupied by a 3D figure as measured in cubic units (as inches, quarts, or centimeters) Volume Volume= length x width x height • Example: Find the volume of the box shown.

  30. Probability • Using the spinner shown above, what is the probability of landing on an even number?

  31. Let’s Finish the Classwork from last time.

  32. Nice work, Mathletes!
