When you reflect, which properties are true?

• length of a side of the shape is the same as to the line of symmetry

• distance from line of symmetry is the same from a point as it is to it's image

• connecting vertices should make a line perpendicular to the line of symmetry

• connecting vertices should make a line parallel to the line of symmetry

• the shape and it's image should be congruent (same size and shape)

Where do you see the angle of rotation when you rotate a shape around a center?

• an angle outside of the shape

• an angle in the shape

• an angle on a stop sign

• an angle formed by the vertex, center and image

Does this image show a rotation? If so, what is the angle of rotation?

• 90° counterclockwise

• 180° counterclockwise

• 270° counterclockwise

• Not a rotation
