I can describe how a figure moves and turns to get from one position to another.

I can identify corresponding points before and after a transformation.

I know the difference between translations, rotations, and reflections.

I can decide which type of transformations will work to move one figure to another.

I can use grids to carry out transformations of figures.

I can use the terms “translation,” “rotation,” and “reflection” to precisely describe transformations.

I can apply transformations to points on a grid if I know their coordinates.

I can apply transformations to a polygon on a grid if I know the coordinates of its vertices.

I can decide whether or not two figures are congruent using rigid transformations.

I can decide using rigid transformations whether or not two figures are congruent.

I can use distances between points to decide if two figures are congruent.

If I have two parallel lines cut by a transversal, I can identify alternate interior angles and use that to find missing angle measurements.

I can determine whether three angles could make a triangle using their sum.

I can explain using pictures why the sum of the angles in any triangle is 180 degrees.

I can repeatedly use rigid transformations to make interesting repeating patterns of figures.

I can use properties of angle sums to reason about how figures will fit together.
