2. 2. Table of Contents Points LinesRays Line Segments Angles “Choose one of the topics above to begin.” “When you are ready to begin another topic click on me at the bottom of the screen to come back to the table of contents.” Standards Citations
3. 3. More info here! POINT A point is a location in space.Watch movie! Capital letters are used to name points. M A G K Table of Contents
4. 4. LINE SEGMENT Quiz Me!More info here! A line segment is made up of 2 points and the straight path between them. N This line segment is called: D ND or DNThe two points at the ends of a linesegment are called endpoints. Table of Contents
5. 5. Quiz Me! 1. What is the name of this geometric figure? A. Line M B. Line Segment E C. RayBACK Table of Contents
6. 6. Try Again What is the name of this geometric figure? A. Line M B. Line Segment E C. Ray Need a little help?BACK Table of Contents
7. 7. Fabulous!What is the name of thisgeometric figure? M B. Line Segment You remembered a line segment is made up of 2 E points and the straight path between them! Table of Contents
8. 8. More info here! LINE Quiz Me! A line is a straight path that goes on forever in both directions. R and J are points, not end R points! J This line is called: RJ or JRThe arrowheads symbolize the line continuing forever,even though it looks like it stops at the arrowheads. Table of Contents
9. 9. Quiz Me! What is the name of this geometric figure? A. Line H B. Line Segment C. Ray ZBACK Table of Contents
10. 10. Try Again What is the name of this geometric figure? A. Line H B. Line Segment C. Ray Z Need a little help?BACK Table of Contents
11. 11. Superb!What is the name of thisgeometric figure? A. Line H You remembered a line is a straight path that goes on forever in both directions! Z Table of Contents
12. 12. More info here!RAY Quiz Me! A ray is a straight path that has a starting point and goes on forever in one direction. This ray is called: B WB This is point B The endpoint is always the first W letter in the name of a ray! This is endpoint WNote the difference between point and endpoint! Table of Contents
13. 13. Quiz Me! 3. What is the name of this ray? A. OD D B. OD O C. DOBACK Table of Contents
14. 14. Try Again 3. What is the name of this ray? A. OD D B. OD O C. DO Need a little help?BACK Table of Contents
15. 15. Fantastic!3. What is the name ofthis ray? A. OD D You remembered that the endpoint is always the first letter in the name of a O ray! Table of Contents
16. 16. More info here! ANGLE An angle is formed by 2 rays or 2 line segments that share the same endpoint. The rays or segments are called the sides ofThe endpoint where the rays or the angle. segments meet is called the vertex of the angle.NEXT Table of Contents
17. 17. Naming Angles The vertex of the angle must always be in the middle of the, between the points A on the sides. C This angle is called: ABC B The vertex point is B. That is why B is or CBA in the middle of the sides A and C.BACK NEXT Table of Contents
18. 18. More info here! Classifying Angles Quiz Me! Acute Angle Right Angle Obtuse Angle Measures between Measures exactly Measures between 0 and 90 90 90 and 180 Straight Angle Reflex Angle Measures exactly Measures between 180 180 and 360BACK Watch movie! Table of Contents
19. 19. Quiz Me! 4. What is the classification of this angle? A. Acute Angle B. Reflex Angle C. Obtuse AngleBACK Table of Contents
20. 20. Try Again 4. What is the classification of this angle? A. Acute Angle B. Reflex Angle C. Obtuse Angle Need a little help?BACK Table of Contents
21. 21. Awesome!4. What is the classificationof this angle? You remembered that C. Obtuse Angle an obtuse angle measures between 90 and 180 ! Table of Contents
