HW #7
Make a graph out of the table you completed during the lab today, such as the one posted on the link below. Your X-axis is Stage Numbers (how many times you added the 40 beans), and the Y axis is height (in mm). Your X axis might go to 7, or 10, or 14, or however many times you added the 40 beans. Your Y axis might go to 10, or 20, or 40 mm, or however tall you measured. The first point, for example might be (1,3), meaning when you added the 40 beans the first time, you measured 3 mm tall.

Unit 1 Review-- IF YOU CAN DO ALL OF THESE, YOU CAN HANDLE THE TEST! Extra Credit if completed and turned in MONDAY!
Unit 1 Review
a.
What transformations to triangle B would produce
triangle A?
b.
What transformation of triangle E would produce
triangle C?
a.
What type of transformation occurred above? Be
specific in your answer (ex: reflected over ____ axis, translated _ units
up/down and _ units to the right/left, rotated ___ degrees clock/counter-clock wise, dilated with a
scale factor of __).
a.
If you translated figure ABC two units to the
left and one down, what would be the new coordinates of point A?
b.
If you translated figure ABC three units to the
left and four down, what would be the new coordinates of point B?
c.
If you rotated ABC 90 degrees clockwise about
the origin, what would the new coordinates of point C be?
d.
If you rotated ABC 180 degrees about the origin,
what would the new coordinates of point A be?
e.
If you reflected ABC over the y-axis, what would
the new coordinates of point B be?
f.
If you reflected ABC over the x-axis what would
the new coordinates of point C be?
a.
The N on the left is the original image. The N
on the right is the transformed image. What transformation occurred?
b.
Are the letters congruent?
c.
How do we know they are congruent?
5. When a figure is dilated, the resulting figure
is similar, congruent, or altogether different from the original figure?
6. When a figure is rotated, the resulting figure
is similar, congruent, or altogether different from the original figure?
7. When a figure is reflected, the resulting figure
is similar, congruent, or altogether different from the original figure?
8. Point A is (2,8),
point B is (8,8), point C is (8,4), and point D is (2,4).
a.
Graph these points onto a coordinate grid and
connect them to form a rectangle.
b.
If rectangle ABCD is dilated with a scale factor
of ½ to form rectangle A’B’C’D’, what would the new coordinates of A’, B’, C’,
and D’ be?
c.
Graph these new points on the same grid and
connect them to form a new, smaller rectangle.
d.
Is this new rectangle A’B’C’D’ similar to or
congruent to the original rectangle ABCD?
i.
How do you know? Support your answer.
a. What is the measure of the third, unmarked angle of the triangle?
b. What is the measure of angle D? Justify your answer using the vocabulary
term that describes it's relationship to another angle.

Complete number 3.
Draw the picture if it helps you to figure it out...
**Remember, when you move to the left and right, you are moving along the X axis. When you move up and down, you are moving along the Y axis. As you answer this question, consider how these shifts will affect the X and Y coordinates of the points of the new figure.
