- 15. UNDEFINED TERMS 15 Undefined termsare the fundamental building blocks that cannot be defined using other geometric terms. They are accepted as understood without formal definitions. The three primary undefined terms in geometry are: Point, Lines, and Plane.

- 17. 17 Term Figure DescriptionNotation Point • A ⁃ A point suggests an exact location in space. ⁃ It has no dimension. ⁃ We use a capital letter to name a point. point A

- 19. 19 Line J D • •m ⁃ A line is a set of points arranged in a row. ⁃ It is extended endlessly in both directions. ⁃ It is a one-dimensional figure. ⁃ Two points determine a line. That is, two distinct points are contained by exactly one line. ⁃ We use a lowercase letter or any two points on the line to name the line. line m or JD
- 20. 20 Note: The points thatlie on the same lines are called collinear points.

- 22. 22 Plane ⁃ Aplane is a set of points in an endless flat surface. ⁃ The following determine a plane: (a) three non-collinear points; (b) two intersecting lines; plane A, plane XYZ or XYZ • Z • Y A • X
- 23. 23 (c) two parallellines; or (d) a line and a point not on the line. ⁃ We use an uppercase letter, script letter, such as A, or three points on the plane to name the plane.

- 25. MECHANICS 1. The teacherwill show a picture from the Mystery Box. 2. Look at the picture carefully and discuss with your group. 3. Decide whether the picture represents a POINT, LINE, or PLANE. 4. Once your group agrees on an answer, raise your group’s stick immediately.
- 26. MECHANICS 5. The firstgroup to raise their stick and give the correct answer will receive a "recitation stab". 6. The recitation stabs you earn will count as "plus points for graded recitation at the end of the quarter". Remember to work together as a team and participate actively!

Once your group is ready, "act out your emoji" andd "raise your emoji card" at the same time so I can see and hear which group goes first. 4. The first group to act out their emoji, raise their card, and give the correct answer will get a "recitation stab".

- 31. 31 Presentation title Instructions 20XX 2.Answer this question How can you determine the connection of a point, line and plane?. 1. Look around your room. Identify and list 5 objects that would model each undefined term. Then look for a design ( furniture, gadgets, personal belongings, etc.) draw it and identify the parts that models each of the undefined terms through labeling.
- 32. 32 Presentation title Instructions 20XX 5.You have 5 minutes to finish this task.
- 34. Points, lines andplanes are very important in our lives. We must integrate the value of critical thinking, perseverance and analytical geometry skills in points, lines and planes by empowering individuals to tackle the real- world challenges efficiently, optimizing spatial reasoning, problem- solving and innovation.
- 35. Direction: (Answer in 1/4sheet of paper) 1. 2. Determine what undefined term is being modeled by each picture. Write POINT, LINE AND PLANE only.
