Given point B is not on line m, suppose B is reflected across line m. Which of the following is true?
BB' is the bisector of line m.
Line m is parallel to BB'.
Line m is the perpendicular bisector of BB'
B=B'
Point T is at (−6, 4). What are the coordinates of point T′ after R y − a x i s ∘ R x − a x i s?

If a figure is translated with the ruleT < − 3 , 3 >
, which translation moves the image back to the original position?
T < − 3 , 3 >
T < 3 , − 3 >
T < 0 , 3 >
T < 3 , 0 >
Given the regular polygon shown, select all of the rotations and reflections that carry the figure onto itself.
a rotation of 120° around the center, point d
a reflection across line c, through the midpoints of opposite sides
a reflection across line a, through a vertex and a midpoint of an opposite side
a reflection across line b, through one vertex, the center d
a rotation of 60° around the center, point d
For a rotation r(x°, p) , which of the following is not true?
For a preimage point A, m∠APA′=x°.
The transformation rotates every point in the preimage x° about a point P.
For the a preimage point A, PA=PA′.
The expression r ( x° , P ) A = B
means that when point P is rotated x° around point A its image is located at point B
