The point (3, -2) is shown on the graph. What are the coordinates of the image of this point after a reflection across the y-axis?
(-2, -3)
(2, -3)
(3, 2)
(-3, -2)
Which of these sequences of transformations will always return a figure to its original position?
Reflect over line m, then reflect over line m again.
Translate 2 units up, then translate 2 units up again.
Rotate 90° counterclockwise around point B. Then rotate 90° counterclockwise around point B again.
Rotate 100° counterclockwise around point B. Then rotate 80° counterclockwise around point B.
Omari and Eva each made a design using four triangles. Select all of the true statements.
The largest triangle in Omari’s design is congruent to the largest triangle in Eva’s design.
Each triangle in Omari’s design has a congruent triangle in Eva’s design.
If you translate Omari’s design 10 units to the right, you get Eva’s design.
Omari’s design is congruent to Eva’s design.
Which transformation sequence will make polygon A congruent to polygon B?
Rotate polygon A 180° counterclockwise around its bottom-right point and then translate 4 units to the right.
Reflect polygon A over the y-axis and then translate 2 units up.
Rotate polygon A 90° clockwise around its center and then translate 3 units to the left.
Translate polygon A 5 units down and then reflect over the x-axis.
Is figure C congruent to figure D?
Yes, they are congruent.
No, they are not congruent.
Is figure E congruent to figure F?
Yes, because I can reflect and rotate figure E, and then translate it onto figure F.
No, because figure E and figure F are not identical.
Yes, because figure E and figure F do not have the same area.
No, because figure E and figure F have different shapes.
Lines AB and CD are parallel. Determine the measures of the three missing angles in the diagram. (Angles are <FBA, <CFD, and <CDF)
37°, 112°, and 31°
31°, 47°, and 143°
31°, 37°, and 149°
33°, 31°, and 143°

Side JL is congruent to sides LM.
Side KN is congruent to sides JL.
Side MN is congruent to sides LM.
