Presentation Transcript

### Geometry Jeopardy

Lines in the Coordinate Plane

GEOMETRY JEOPARDY CATEGORIES

Lines and

Planes

Parallel, perpendicular, and skew lines and planes.

Special

Angles

Angles related to transversals.

Postulates

Theorems

Complete postulates and theorems.

Slope

Interpret/apply facts about slope.

Equations

Interpret/write equations of lines.

~Rules~

- Teams will answer questions in random order
- Each team will have the same number of turns
- Teams will have 30 sec. to answer a question
- If a team answers a question incorrectly, the next team will get a chance to steal the points
- The team with the most points at the end of the game will win 5 extra credit points on our next test (for each team member.) The second place team will receive 4 points. Then 3 points, etc.
