To solve this problem,
you will need to understand two important parts of
the problem before even getting started. First, you
need to know what it means to find lines of symmetry.
Remember, a line of symmetry is a line through a
figure that when the figure could be folded on that
line both sides will line up and be the same size
and shape.
The second part you will need to be able to do is
to recognize the geometric figure given to you. The
figure is an equilateral triangle where all three
sides are the same length.
 Since you fully understand the question, it is time
to solve the problem. One strategy in solving this
one may be to draw a picture of the triangle or use
the one given and begin to draw in lines where what
is on one side of the line it is also on the other
side.
You see by your picture that there are three lines
of symmetry for this figure. If you were to fold
along any of those three lines the parts of the
triangle would match up perfectly. Therefore, for the first
point for this problem, you would identify the answer
to the question to be letter D, 3 lines of symmetry.
For the second point, in order to support your
answer you could include your drawing where
you drew the three lines of symmetry or you may
include a short paragraph explaining what symmetry
is and that the three lines you found would work
for if you could fold along those lines. Be sure
you are clear and that you express your understanding
of finding lines of symmetry. |
