REINFORCE Find a geometric representation for the following sequence of numbers. 3, 4, 5, 6, 7, … X+1 2. What are the three undefined terms in geometry? Point,line,plane 3. Write a description of a point. How are points labeled? A marker that labels a specific point. 1 capital letter 4. Write a description of a line. How are lines labeled? Extens forever in both directions. 2 Capital letters and a line symbol AB 5. What are two names for the line containing points A and E?

Describe the difference between a line and a line segment. A line goes off forever in both directions A line segment is a piece of line between two points. 7. What is meant by the notations AE, AE, and AE? A E= Distance A E= A line segment that stop at A and E. A E = A line containing points A and E. 8. Write a definition of ray. Starts at a point and goes forever in one directions. 9. How do you name a ray in geometry? What is the name of a ray with endpoint I and point J on the ray? Put a ray above the letters IJ or JI 10. Write a definition of angle. An angle is two rays with a common vertex 11. REINFORCE How are ∠DBG and m∠DBG different? DBG names an angle m DBG is a measurement of the angle Copyright 2015 Agile Mind, Inc. ® Content copyright 2015 Charles A.

Write a description of a plane in geometry. A plane is a flat surface that extends forever in all direction (floor) 13. What is the minimum number of points needed to determine a line? A plane? Line =2 Plane=3 14. REINFORCE a. Name two points in the room diagram that are collinear with points C and F. Points on the same line. QR b. Point J is noncollinear with points H and K. Name another point that is noncollinear with points H and K. Points not on the the same line IJ c. Points C, Q, and S are coplanar points. Name another point on the floor that is coplanar with C and Q. Points on the same plane CQE d. Points A, B, and F are noncoplanar with point C. Name another point in the room that is noncoplanar with A, B, and F. Points not on the same plane. Copyright 2015 Agile Mind, Inc. ® Content copyright 2015 Charles A.
