## Do All of the Following Tasks

##### Task 1 Review Basic Terms in Geometry
• It shows you how to explain basic concepts in Geometry using thumbnail definitions.
##### Task 2 Take a Test
2. Fill out the form, then press the Submit button to complete the test.
• When he sees your input data, Mr. Quach will give you a grade for this test.
##### Appendix 1A Thumbnail Definitions for Geometry
1. Circle; that means, the same distance to a center. | Page 6
2. Line segment; that means, all points between two. | Page 6
3. Parallel; that means, two non-intersecting lines. | Page 12
• Parallel lines by drawing two perpendicular lines | Page 40
4. Perpendicular bisector; that means, a perpendicular line through the midpoint | Page 18
5. Conjecture; that means, a tentative basis without proof. | Page 18
6. Inscribed hexagon; that means, every vertex on the circle. | Page 24
7. Bisecting; that means, dividing into two parts.
8. Angle bisector; that means, an angle bisecting line. | Page 32
9. Congruent; that means, identical in form.
10. Congruent segments; that means, line segments of equal length. | Page 49
11. Square; that means, four congruent segments. | Page 49
12. Polygon; that means, a plane figure with at least three straight sides and angles.
13. Equilateral; that means, all sides congruent.
14. Equiangular; that means, all angles congruent.
15. Regular polygon; that means, equilateral and equiangular. | Page 49
16. Tessellation; that means, surface covering. | Page 65
17. Assertion
18. Rotation; that means, a center and a directed angle.
19. Perpendicular; that means, at an angle of 90 degrees.
20. Reflection; that means, the same perpendicular distance to a line.
