Answer explanation

I can apply _____________________ to points on a grid if I know their _________________.

Use a comma to write out the missing words for the Lesson 4 Learning Goals (page 32):

I can use the terms translation, rotation, and reflection to ________________ describe transformations on a grid.

I can use a grid to _________________ a translation, rotation, or reflection.

 (Lesson 5, Pg 34) What are the coordinates of point A after each transformation?

Rotate  $180\degree$  with center $\left(0,0\right)$  :

•  $(–2,–1)$  

•  $(2,1)$  

•  $(1,–1)$  

•  $(2,–1)$  

•  $(–1,–2)$ 

Select the correct order:

(Lesson 6, page 37) Summary Question How are coordinates useful when describing and drawing transformations?

Coordinates are useful when describing and drawing ____________________ because they communicate the _______________ of the _____________. When describing a transformation, we can specify a _____________________, a point of rotation, or the ___________________ and _________________ of a translation and then use the grid to precisely identify and draw the vertices of the image.

• transformations, location, vertices, line of reflection, distance, direction

• vertices, distance, transformations, line of reflection, location, direction

• line of reflection, location, direction, vertices, distance, transformations

Use a comma to write out the missing words for the facts written on Lesson 7 (page 38):

Here are some facts about congruent figures:

● We _______________ need to check all the measurements to prove two figures are congruent; we have to find a sequence of rotations, reflections, and translations that match up the figures.

● Two figures that look like mirror images of each other can be congruent. There must be a ______________ in the sequence of transformations that matches up the figures.

● Two polygons that have the same area and the same perimeter ______________ always congruent
