1. Draw six segments that pass through every dot in the figure without taking your pencil off the paper. Session 55

2. Go over test

3. Unit 5 Vocabulary

4. Angle An angle measuring less than 90° but greater than 0° The angle is

5. Circle The set of points on a plane at a certain distance, or radius, from a single point, the center

6. Perpendicular Line Two lines that intersect at a right angle (90°). Written as

7. Parallel Line Lines in a plane that either do not share any points and never intersect, or share all points. Written as

8. Line Segment A line with two endpoints. Written as

9. Point Point A or Point B An exact position or location in a given plane.

10. Line The set of points between points P and Q in a plane and the infinite number of points that continue beyond the points. Written as

11. Distance along a line The linear distance between two points on a given line.

12. Right Angle An angle that measures 90°.

13. Acute Angle An angle measuring less than 90° but greater than 0°.

14. Obtuse Angle An angle measuring greater than 90° but less than 180°.

15. One-to-One A relationship wherein each point in a set of points is mapped to exactly one other point.

16. Pre-image The original figure before undergoing a transformation.

17. Image The new, resulting figure after a transformation

18. Isometry A transformation in which the preimage and image are congruent.

19. Rigid transformations can also be referred to as an ISOMETRY. Every segment is congruent to its image. Transformations are called RIGID if every image is congruent to its preimage.

20. Which of the following are rigid transformations? (Isometry)

22. Find the value of each variable, given that the transformation is an isometry.

23. Congruent Figures are congruent if they have the same shape, size, lines, and angles.

24. Similar Triangles Triangles are similar if they have the same shape but have different sizes.

25. Even and Odd Functions

26. Algebraically A function is _____ if All of the exponents of the variable are even. All of the exponents of the variable are odd. A function is ______ if The exponents are a mixture of odd and even

27. BEWARE OF ____________ All constants really have a ___

28. ___ is EVEN!!

29. Graphically A function is ____ if A function is _____ if The graph reflects across the ___-axis (means you can fold it ________ style and it would match up). The graph has _____  rotational symmetry about the ________ (means you could turn it ________-down & it would still look the _________...it must go through the _________).

30. Even, Odd or Neither? Ex. 1 Algebraically
