Hello, Mr G here. Welcome to today's program.
Let's go to the IMF aside and see what's on the agenda for today.
Tess Elation. What is a test? Elation. You
see them every day. Look at this paved driveway. Do
you see the shape that is repeated? But this is what we call a
test elation. It's a repeated arrangement of a
congruent or equal shape without any gaps or
overlaps. How about this tiled
bathroom wall? Do you see the square that is
repeated in our last example?
I'm sure you remember this pattern as a regular hexagon.
Can you guess where we found it? If you said on an
overpass on Highway 5 95 you'd be correct,
Son polygons. Also Tessa late. Let's look at a few
samples of polygons, which do Tessa late.
Our first example shows a group of triangles which air test elated,
noticed that there are no gaps or overlaps.
To illustrate this, I'll take two shapes which are exactly
alike. Notice when I try to lay them side by side.
You see gaps. If I lay
them so that there is no gaps, you see that they
overlap. Therefore, these two identical shapes
Do not test a late. Can you identify the type of
triangle used? Yes, they are equal
lateral triangles. Notice also because of the
way these triangles air colored that you can also identify
another shape, which we learned about called the rhombus.
Or if I turned to paper sideways, you can see that that
rhombus is a parallelogram.
In our second sample, we see regular hexagons.
They are six sided polygons, with six sides equal in length
and six angles equal and degrees again, the
polygons fit together without gaps or overlaps.
A combination of polygons used together can also be test.
Elated noticed that this example shows
regular Octagon tze and squares combined to
create a test elation.
It is not necessary to use on Lee polygons to create Tess
relations. Here are some samples created by my students.
Let's look at them and then I'll show you how you can create your own
desolation. Our first example
shows a rather simple test elation, and then the colors were
added later to add interest to the test elation.
Let's look into 2nd 1 now. The second one's a little more
involved. You can use your imagination and try to figure out what the
student was trying to relay.
Let's look at the 3rd 1 This is one of my favorites.
Notice The test elation is colored to look like different faces.
Very interesting. Now let me show you how to
create your own test elation.
I begin with a three inch by three inch piece of tag board or
card stock. I labeled a sight I'm using as
a I draw design at the
top of Side A and label it one.
Then I choose one of the sides and draw another design and
label it two. Notice the two
designs. I then cut out Section
one and slide it straight down
and tape it to the bottom of Side A. I made sure that the
straight sides fit tightly together before I taped them. Did
you notice that the bottom of side A looks just like the
opposite of the top of side A.
Next, I cut out Section two and slid this section
straight across to the opposite side and tape it.
I again make sure that the straight edge is fit tightly together
before taping. It looks like this.
My pattern is now complete
How are you doing? I hope you're able to follow along.
I then take my pattern and trace it onto a piece of paper.
Later off. Color it. Notice it.
Pattern fits neatly on the paper with no gaps and
no overlaps. Therefore, it's a test elation
as you create your own test. Il ations be creative in your
designs. However, don't make them so complicated that you
cannot cut them out. Philip, your entire paper
with your design. As you trace your design, it will run off your
paper. Now that's to be expected. Just make sure your
sections fit together perfectly. Otherwise
you'll have gaps. Since this is
our last time together in this series, I want to let you know
how very much I've enjoyed presenting these programs.
I hope you had fun and learned a lot. I know I did keep
practicing your constructions and put to work the things you've
learned. I'm going outside now to chart my next
destination. Come on along.
Gee, everything looks great out here. I think I'll practice
my transformations
