Pitanje 1
1.

Translate the figure 2 units left and 2 units down.

A (1,3) --> A'

B (4,3) --> B'

C (2,-1) --> C'

Pitanje 2
2.

Draw the reflection of the figure over the x-axis.

Perform the transformation and then write the coordinates into the correct box.

A(-2,-4) ---> A'

B (1,-3) ---> B'

C(3, -4) ---> C'

Rotate the figure 180° about the origin.

D (-4, -1) ---> D'

O (2, -3) ---> O'

G(1, -4) ---> G'

On the coordinate plane shown, Segment AB is a vertical segment with a length of 5 units.

If Segment A'B' is the image of Segment AB after a rotation, which must be true about Segment A'B'?

The vertices of a triangle are M(−2, 1)​ , I(1, 0)​, A(−3, 2)​.

Draw the image after a dilation with a scale factor of 2.

Enter the coordinates of the image in the appropriate boxes.

The red figure is similar ot the blue figure.

Complete the description of a similarity transformation between the figures.

One possible similarity transformation is to dilate the red figure with respect to the origin using a scale factor of -axis.

Extra Credit

Rotate the figure 90° counterclockwise about the origin (show in BLUE), and then reflect in the x-axis (show in PINK).
