Front

New coordinates of D(4,6) after dilation centered at origin with scale factor 1/2?

Back

D'(2,3)

Front

What is the scale factor of this dilation?

Back

3

Front

Which of the statements is true about the graphed triangles?

Back

They are similar, because one can be obtained by dilating the other about the origin with a scale factor of 1/2.

Front

The pair of figures is similar. Find the missing side.

Back

x = 5

Front

What makes isometric (rigid) transformations different than similarity transformations?

Back

Isometric transformations have the same shape AND size, similarity transformations just have the same shape.

Front

Why is Quad OBCD similar to Quad OHTE?

Back

Quad OBCD can be reflected over the y-axis and then dilated about point O by a scale factor of 2.

Front

Why is ΔOBC similar to ΔOGT?

Back

ΔOBC can be dilated about point O by a scale factor of 1/2, and then rotated 90 degrees about point O.
