Lesson 03: Grid Moves | Unit 1: Rigid Transformations and Congruence

Draw

Apply a translation to Figure A which takes $$P$$ to $$P’$$ . Use the image to demonstrate the translation.

Draw

Apply a counterclockwise rotation of Figure A, using center $$P$$ , of $$60^\circ$$ . Use the image to demonstrate the rotation.

Draw

Apply a reflection of Figure A across line $$\ell$$ . Use the image to demonstrate the reflection.

Draw

On the grid, draw a rotation of triangle $$ABC$$ .

Multiple Choice

How was the rotation of triangle $$ABC$$ performed?

• The rotation was performed around point B.
• The rotation was performed around the centroid of the triangle.
• The rotation was performed around point A.
• The rotation was performed around point C.

Draw

On the grid, draw a translation of triangle $$ABC$$ .

Multiple Choice

How was the translation of triangle $$ABC$$ performed?

• The translation was performed by reflecting triangle ABC.
• The translation was performed by shifting each vertex of triangle ABC.
• The translation was performed by scaling triangle ABC.
• The translation was performed by rotating triangle ABC.

Draw

On the grid, draw a reflection of triangle $$ABC$$ .

Multiple Choice

How was the reflection of triangle $$ABC$$ performed?

• The reflection of triangle ABC was performed by mapping each vertex across a line of reflection.
• The reflection was done by rotating triangle ABC.
• The reflection was achieved by scaling triangle ABC.
• The reflection involved translating triangle ABC.

Draw

Reflect Polygon P using line $$\ell$$ . Annotate the image to show the reflection of Polygon P across the line $$\ell$$ .
