14. a] Could you list all the numbers between 1 and 2?
No There are an infinite number of fractions between 1 and 2.
b] Is there a point on the number line for every
number between 1 and 2?
Yes
c] Is there a limit to the number of points between
1 and 2?
No
There is always a point between any
two points on the segment ST.
The point in between is the midpoint.
State whether the figures appear to be congruent
(that is, appear to have the same size and shape.

15.
Yes
17.
No
Yes
Not the same size.
Yes, mirror line
18. No
19.
Note the same shape.
Yes, mirror line

21. Draw 2 points P and Q on a sheet of paper. Fold the paper so that the
fold line f contains both P and Q. Now fold so that P falls on Q. Call the
second fold g. Lay the paper flat and label the intersection of f and g as
point X. How are points P, Q and X related? Explain?
X is the
midpoint of
PQ because
…
PX falls on XQ
PX  XQ
22. If AB = BC, must point B be the midpoint of

There are an infinite
number of points
that will work that
are not midpoints.
C
All of them are on
the red line.
Given the numbers are coordinates of two points
on a number line. State the distance between the
points.
