2. 2 parallel lines Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * never intersect * always the same distance apart examples:

3. 3 perpendicular lines Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * 2 lines OR 2 line segments OR 2 rays that intersect * form right angles at point of intersection

4. 4 intersecting lines Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * 2 lines OR 2 line segments OR 2 rays that cross

5. 5 point Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example:. D = point D * identifies a location * shown with a small, colored circle * usually named by a capital letter

6. 6 vertex Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * a point where lines meet * a point where rays meet * a point where edges of a polygon meet * plural form = vertices

7. 7 line Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * a straight path * extends in both directions * no endpoints

8. 8 line segment Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * part of a line * has 2 endpoints

9. 9 ray Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) example: * part of a line * has one endpoint * continues in ONE direction without end

10. 10 congruent Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * having the same size and same shape * congruent angles have same measure * congruent line segments have same length

11. 11 polygon Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * a closed plane figure * having 3 or more straight sides examples:

12. 12 quadrilateral Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * a closed plane figure (polygon) * has 4 sides examples:

13. 13 parallelogram Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * a closed plane figure (polygon) * has 4 sides (quadrilateral) * pair of opposite sides are parallel * pair of opposite sides are congruent example:

14. 14 rhombus Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * a closed plane figure (polygon) * has 4 sides (quadrilateral) * opposite sides are parallel (parallelogram) * 4 sides are congruent (equal in length) example:

15. 15 trapezoid Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) * a closed plane figure (polygon) * has 4 sides (quadrilateral) * has only ONE pair of parallel sides example:

16. 16 quadrilateral chart Geometry enVision Topic 8 PA Assessment Anchor M5.C (review Grades 3 & 4 Anchor Glossary) quadrilateral trapezoid parallelogram rectangle square rhombus
