Which of the following is a way to prove that triangle ABC is congruent to triangle FED?

• Rotation of 180 degrees in the middle of vertices c and d.

• Triangle ABC can be translated down two units, right 3 units and then reflected over a vertical line that goes through point d.

• A single reflection over a vertical line halfway between the two triangles.

• Triangle ABC can be translated down two units and then reflected over a horizontal line that goes through point d.

For each pair of shapes, decide whether or not quadrilateral ABCD is congruent to quadrilateral EFGH. Explain your reasoning.

• Yes, rotate quadrilateral ABCD 180 degrees using point d as the center, then translate 1 unit right and 2 units down.

• Yes, rotate quadrilateral ABCD 90 degrees counterclockwise using point d as the center, then translate 1 unit right and 2 units down.

• No, there are no sets of transformations that would map/overlap quadrilateral ABCD onto quadrilateral EFGH because the shapes are not congruent.

Are the two shapes congruent?

• No, there are no sets of transformations that map/overlap the top triangle onto the bottom triangle because the shapes are not congruent.

• Yes, you can make the top triangle smaller, then reflect it over a diagonal line.

• Yes, you can reflect the top triangle over a diagonal line.

• Yes, rotate the top triangle 60 degrees clockwise, then translate it down.

Are the two figures congruent?

• Yes, you can rotate figure A 90 degrees clockwise to line up with figure B.

• No, these two figures are not congruent through transformations because the side lengths and angles are not equal.

Triangle NOL is the image of triangle LMN after a 180 degree rotation around the midpoint of segment LN. Triangle QNM is the image of triangle LMN after a 180 degree rotation around the midpoint of segment MN. Explain why OQ and LM are parallel.

• If you rotate a line 180 degrees around a point ON the line, then you will have parallel lines.

• If you rotate a line 180 degrees around a point NOT on the line, then you will have parallel lines.

• If you rotate a line 90 degrees around a point NOT on the line, then you will have parallel lines.

• If you rotate a line 90 degrees around a point ON the line, then you will have parallel lines.
