Unit 2 Review

Corresponding angle measurements stay the same when the figures are...

• Congruent

• Similar

• Different

• triangles

Tags

CCSS.8.G.A.2

Similar figures can be proven to be similar by...

• Mapping the figure on to the image with rigid transformation

• Mapping the figure on top of the image

• Mapping the figure on top of the image with a sequence of transformations

Dilations .....

• are A type of transformation

• always change the size of the shape

• Change the distance from the center of dilation

• change the corresponding angle measurements

CCSS.8.G.A.3

Using a scale factor

• can make the distance larger/shape larger

• can make the distance smaller/shape smaller

• can keep the distance the same/shape the same

• Doesn't change anything

CCSS.7.G.A.1

Similar triangles...

• Must have only 1 corresponding angle that is congruent

• Must have at least 2 corresponding angles that are congruent

• Must have 0 corresponding angles that are congruent
