Multiple Choice

Explain?

• No, rigid transformation preserves both distance & angle measure.

• Yes, since the angles and sides are the same length.

Multiple Choice

What are the images?

• $$\angle F'\ is\ the\ image\ of\ \ \angle F.\ \ \angle H'\ is\ the\ image\ of\ \angle H.$$

• $$\angle F'\ is\ the\ image\ of\ \ \angle H.\ \ \angle H'\ is\ the\ image\ of\ \angle F.$$

Multiple Choice

What are the pairs of corresponding sides?

• $$\overline{EF}\ and\ \overline{E'F'}\ \ \overline{FG}\ and\ \overline{F'G'}$$

• $$\overline{EF}\ and\ \overline{F'G'}\ \ \overline{FG}\ and\ \overline{E'F'}$$

Multiple Choice

State the translation.

• Translate each x-coordinate 2 units to the left and each y-coordinate 5 units down.

• Translate each x-coordinate 2 units to the right and each y-coordinate 5 units up.

Multiple Choice

What is the coordinate rule?

• $$T_{<8,-2>}\left(x,y\right)=\left(x+8,\ y-2\right)$$

• $$T_{<8,2>}\left(x,y\right)=\left(x+8,\ y+2\right)$$

Multiple Choice

Is the transformation a rigid transformation?

• Yes; distances between corresponding pairs of points are equal.

• No; distances between corresponding pairs of points are not equal.
