8th Unit 1 Review 21-22

Vertical Angles are

• sometimes congruent

• Always congruent

• Always similar

• Similar on weekends

What is the measure of angle X?

• 451 degrees

• 115 degrees

• 81 degrees

• 65 degrees

Which transformation could be used to show that figure A (on the left) is congruent to figure B (on the right)?

• rotation and reflection

• reflection and reflection

• translation and reflection

• dilation and reflection

The figure A is transformed to figure B by

• 90 degrees counter clockwise rotation

• Refection across the x-axis and then a reflection across the y-axis.

• Translation to the right and then down

• 360 degree rotation around the origin

If you were to say that two shapes are congruent, what would that mean?

• The same size and shape

• A shape that has been enlarged and moved to the right

• A shape that has been reflected and then translated

• A shape that is larger, but is the same shape

Another word for a reflection

• A slide to the left or right on the corrdinate plane.

• Scary

• Flop around the x-axis

• Flip over a line

What is another word for a translation?

• A dilation

• A slide

• A flip

• A turn

Rotation means

• to flip a figure across an axis on the coordinate plane

• to turn a figure around a point

• to slide a figure up or down, or to the left or right

• to make a figure larger or smaller

What transformations could be used to move figure A to figure B?

• Reflect over the x axis and the rotate 90 degrees clockwise

• Rotate 90 degrees counter clockwise and then translate to the right

• Reflect over the y-axis and then translate to the right and up

• Rotate 90 clockwise and the translate to the right

Which transformations could you use to show that figure A is congruent to figure B?

• rotation and then translation

• reflection and then translation

• translation and then dilation

• Reflection and then rotation
