figures?

• Rigid Transformation

• Non- Rigid Transfomations

• Rigid followed by non-Rigid

• It doesn't really matther

Multiple Select

Will rigid or non-rigid transformations produce Similar figures?

• Rigid Transformation

• Non- Rigid Transfomations

• Rigid followed by non-Rigid

• It doesn't really matther

Open Ended

Use the definition of congruence in terms of rigid motions to prove rectangle ABCD is congruent to rectangle A'B'C'D'

(what tranformations would make the figures line up)

Multiple Select

In the graph below, ΔMNO is the image of Δ𝐵AC after a

rotation of 270° counterclockwise about the origin.

Which statements below are true? Select all that apply.

Open Ended

Based on the two similar squares above, name the properties of similar polygons, and prove the figures are similar.

Multiple Choice

Determine whether the polygons are similar, if they are, write the similarity statement and find the scale factor from figure A to Figure B.

• Yes they are Similiar,

  $$k=2.5$$

• YEs they are Similiar, $$k=0.4$$ $$$$

• Not similar

Multiple Choice

Determine whether the polygons are similar, if they are, write the similarity statement and find the scale factor from figure A to Figure B.

• Yes they are Similiar,

  $$k=\frac{3}{4}$$

• YEs they are Similiar, $$K=\frac{4}{3}$$ $$$$

• Not similar

Multiple Choice

Determine whether the polygons are similar, if they are, write the similarity statement and find the scale factor from figure A to Figure B.

• Yes they are Similiar,

  $$k=\frac{8}{5}$$

• YEs they are Similiar, $$K=\frac{5}{8}$$ $$$$

• Not similar

Multiple Select

The larger Popsicle is a dilation of the smaller Popsicle stick. Select ALL statements that are true.

(Hint: there are 4)

• The scale factor of the dilation is $$\frac{3}{2}$$

• Point L is the center of Dilation

• $$\Delta LOV\sim\Delta LEY$$

• $$3\left(LV\right)=2\left(LY\right)$$

• $$\frac{LO}{OE}=\frac{OV}{EY}$$
