Front

How many lines of symmetry does a trapezoid have?

Back

0

Front

Which of the following is NOT a rigid transformation? (Rotation, Translation, Reflection, Dilation)

Back

Dilation

Front

Triangle ABC is dilated to create Triangle A'B'C'. What is the rule for this transformation? (x,y) to (.5x, .5y), (x,y) to (x + 4, y + 2), (x,y) to (-x, y), (x,y) to (3x, 3y)

Back

(x,y) to (3x, 3y)

Front

If a turtle moves from coordinate P = (3,2) to Q = (5,6), which vector models the turtle's motion? 〈-2,-4〉, 〈2,4〉, 〈8,8〉, none of these

Back

〈2,4〉

Front

The __________ is the ratio of a length of the image to the corresponding length on the original figure.

Back

scale factor

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including rotation, translation, and reflection.

Front

Define dilation in geometry.

Back

A transformation that alters the size of a figure but keeps its shape, defined by a scale factor.

Front

What is the scale factor in a dilation?

Back

The ratio of the length of the image to the length of the original figure.

Front

What is the difference between a translation and a reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips a figure over a line.

Front

How do you determine the coordinates of a point after a translation?

Back

Add the translation vector to the original coordinates.
