Transformations and Properties of Angles

The video covers various lessons on transformations, including moving shapes in a plane, naming moves, grid transformations, making moves with polygons, and coordinate transformations. It explains how to describe and apply translations, rotations, and reflections using frames, cards, grids, and coordinates.

What transformation occurs when a shape moves vertically from one frame to the next?

• Dilation

• Rotation

• Reflection

• Translation

Which pair of cards shows a shape and its image after a reflection?

• Cards 1 and 4

• Cards 4 and 5

• Cards 3 and 5

• Cards 2 and 6

Which transformation involves flipping a shape over a line?

• Dilation

• Rotation

• Reflection

• Translation

How does a shape change when it is rotated 90 degrees clockwise on a grid?

• It enlarges

• It moves to the left

• It flips over a line

• It turns to the right

What is the result of rotating a point 180 degrees around the origin?

• The point moves to the adjacent quadrant

• The point moves to the same quadrant

• The point moves to the opposite quadrant

• The point remains unchanged

What is the result of a rigid transformation?

• The shape becomes distorted

• The shape remains congruent

• The shape changes orientation

• The shape changes size

What is the scale factor if a shape is enlarged to twice its size?

• 3

• 2

• 1

• 1/2

How do you determine if two shapes are congruent?

• They have the same color

• They can be mapped onto each other using rigid transformations

• They have the same perimeter

• They have the same area

What is the measure of an angle formed by two parallel lines and a transversal?

• It depends on the transversal

• It is always 45 degrees

• 180 degrees

• 90 degrees

What is the relationship between alternate interior angles?

• They are different

• They are equal

• They are supplementary

• They are complementary
