Lesson Objectives and Notes: Section 1-1 (G.2.2.1.1):
 Students will use the term equidistant.
 Students will use deductive reasoning to prove facts about a diagram.
1. Do the slants lie on the same line?
2. Are the horizontal lines parallel?
Deductive Reasoning: _____________________________________________________________
Equidistant: ______________________________________________________________________
Suppose that you and Pat are partners in a game in which you must locate various clues to win. You
are told to pick up your next clue at a point that is as far from the fountain as from the oak tree and is
10 m from the flag pole. You locate a point 𝑋, which satisfies both requirements, but grumble
because there isn’t any clue to be found at point 𝑋. Then Pat realizes that there may be a different
location that satisfies both requirements. Can you locate another point that meets both
requirements?

Suppose that you concentrate on points that are equidistant from the fountain and oak tree while Pat
works on points that are 10 m from the pole. In the diagram below, 1 cm represents 2 m, the circle
represents Pat’s points and the line represents your points. If you could not locate another location
does the diagram help in finding another point 𝑌, which meets both requirements?

Classroom Exercises: Refer to the diagram above.
1. Suppose the diagram showed all points that are 5 cm from point 𝑃. What geometric figure would
the points form? __________
2. Is there a point on the line that is 15 cm from points 𝐹 and 𝑇? _______ How many points meet
this requirement? _______
3. It appears as if points 𝑃, 𝑋 and 𝑇 might lie on a straight line. Do they? _______
4. It appears as if point 𝑃 might be equidistant from points 𝑋 and 𝐹. Is it? _______
5. Suppose Pat spoke of a line 𝑙 joining points 𝐹 and 𝑇 while you thought of a line 𝑛 joining points 𝐹
and 𝑇. Is it better to say that lines 𝑙 and 𝑛 are two different lines, or to say that they are the same
lines with different names? __________
6. Point 𝑋 is equidistant from points 𝐹 and 𝑇. Furthermore, point 𝑌 is equidistant from points 𝐹 and 𝑇.
Does that mean that points 𝑋 and 𝑌 are equally distant from point 𝐹? _______
7. Suppose you were asked to find a point 5 cm from points 𝑃, 𝐹 and 𝑇. Is there such a point?
_______
8. Do you believe there is any point that is equidistant from points 𝑃, 𝐹 and 𝑇? _______
