What are the first three types of Rigid Transformations that we learned?

Reflection, Rotation, and Translation

100

Can a rigid transformation take blue triangle to the yellow triangle? If so, which transformation?

No!

100

How do we know if two figures are congruent? (Hint: Do not just say "they are exactly the same.")

If there is a rigid transformation that takes one to the other.

100

How many triangles can be created with a 20 degree, 100 degree and 70 degree angles?

NONE

100

What is the vocab word for two angles that add up to 90 degrees?

Complementary

200

The image shows an example of which transformation?


Translation

200

Does the following image represent a rigid transformation? If so, identify which one.

Yes, a rotation.

200
If two quadrilaterals have the same four side lengths in the same order, are they always congruent?
No! (Example: a rectangle and parallelogram)
200

How many triangles can be created with sides of 7cm, 8cm, and 10cm?

1

200

What is the 3 LETTER NAME of the angle that is equal to angle ZOX?

WOY or YOW

300

The image shows an example of which transformation?

Reflection

300

Name some kind of transformation that IS NOT rigid.

Dilation, slicing, stretching, compressing, etc.

300
You order a small pizza and I order a large pizza. Are they congruent? EXPLAIN
No --> difference sizes
300

Define Congruence

Same shape, same size

300

What is the measure of angle WOX?

115 degrees

400

Please find the line of reflection.

Y-axis or Y=0

400

In order to describe a rotation, you must include what?

The center of rotation (a point), the angle of rotation (how many degrees), and the direction (clockwise or counterclockwise.

400

My triangle has angle measures of 90, 45 and 45 degrees. If you draw a triangle with the same angle measures, does it have to be congruent? EXPLAIN.

No --> could be different side lengths.

400

Define Corresponding

Same thing, same location

400

What is the term for two angles on opposite sides of a vertex, which are always equal in measure?

Vertical Angles

500

Please identify the transformation. (3 pieces of information needed)

Rotation 1:90* 2:Clockwise 3:Around vertices (1,-3)

500

In order to describe a reflection, what must you include?

Line of reflection

500

Imagine two triangles:

In the first triangle, all three angles equal to 60 degrees. In the second triangle, all three angles are equal to 60 degrees.

Is it true that these triangles MUST be congruent?

No, they could be different sizes.

500

What is the difference between congruent and similar?

SIZE

500

What is the word for two angles that add to 180 degrees?
