Transformations Topics Find image given a description of a
translation, reflection, or rotation. Find image given a function describing a
transformation. Determine if the transformation is a translation, reflection, rotation, or none of the above.
Translate figures using directed line segments.

Transformations Topics Reflect over a given line. Rotate 90 degrees or 180 degrees
around a given point. Determine lines of reflectional
symmetry. Understand the concept of rotational
symmetry.

Triangle Congruence Determine if triangles can be proved
congruent by SSS, SAS, ASA, or none of the above.
Write basic two-column proofs proving triangles congruent (MAKE SURE TO INCLUDE THREE CONGRUENCE STATEMENTS!)
Apply properties to prove corresponding parts of triangles congruent.

Transformations Give the image if the point (-1, 5) is
translated up 2 and to the left 3.
Give the image if (-3, 6) is reflected over the y axis.
Give the image if (-2, 5) is reflected over the line y = 2.

Transformations
Give the image if (2, -5) is rotated 90 degrees clockwise about the origin.
Give the resulting image if the function
(x, y) (y, -x) is applied to the point (-1, 4). Is this a translation, reflection, or rotation? Write a function that reflects a point
over the x-axis.
