What do you think of when you hear the word translate?

With your partner, discuss what you think it means to translate an image in geometry.

Translate means “to slide”

Day 4- Dilations

BEllwork After a translations 2 units left and 4 units down. 1.) Find the coordinates for triangle xyz After a reflection across the y-axis. 2.) Find the coordinates for triangle xyz After a rotation 180 degrees about the origin 3.) Find the coordinates for triangle xyz After a translations 2 units left and 4 units down.

Discuss with your neighbor: What do you think of when you hear the word dilate? What do you think it means to dilate an image?

Recap from yesterday

A dilation can be an enlargement or a reduction. To enlarge means: ___________________________ To reduce means:____________________________

The Scale factor tells you what to multiply all the coordinates by. Multiplying by a whole number will _____________ the image. Multiplying by a fraction will ______________ the image.
