You will find more examples in your textbook on the proportionality theorems (8-4). Test on all triangle similarity theorems and postulate will be on Tuesday, Sept. 1st. We will be reviewing on Monday.

Quiz on similar triangles will be on Friday, August 28th. We will be working in groups to practice real world applications of similar triangles and to practice EOC type questions this week. In your textbook, you will find Test Prep questions in sections 8-1 and 8-3 that are excellent practice for the EOC.
For the next few days, we are focusing on the three ways to prove triangles are similar (1) angle angle, (2) side,side,side and (3) side angle side.
Students learned about a new type of transformation that reduces or enlarges a figure called dilation. Two figures are similar if they are the same shape but not the same size. Students learned how dilation and similarity are related and found the scale factor used to create smaller or larger versions of a shape.
Today we learned about rotational symmetry. We learned how to find the angle (s) of rotation that would map a polygon onto itself. Please quiz yourself on the transformations graphic organizer in your interactive notebook for tomorrow's assessment.
Test on Tuesday Rotations skills check was given today.
We rotated figures 90, 180, and 270 degrees both clockwise and counterclockwise today. Notes and practice are found below.
We reviewed all reflections rules and practiced on the coordinate plane. Students were given their translations quiz back today.
We learned how to reflect a figure over the x and y axes and over the lines y=x and y= -x.
We began translations today.
