Properties of Geometric Figures

Identify the transformation from B to D.

• 90^o Clockwise Rotation

• 180^o Rotation

• 270^o clockwise Rotation

• 360^o Rotation

Enlargement or reduction?  Find the scale factor!

• It's a reduction; the scale factor is 2.

• It's an enlargement; the scale factor is 2.

• It's an enlargement; the scale factor is 1/2.

• It's a reduction; the scale factor is 1/2.

Congruent geometric figures have the:

• Same size

• Sides Equal

• Same Size and Same Shape

• Angles Equal

What are the coordinates for A' after a 90^⁰ rotation clockwise?

• (1, 3)

• (3, 1)

• (3, -1)

• (1, -3)

This symbol means congruent

• ≅

• ≠

• ∠

• Δ

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate -90 degrees around the origin

• Rotate -90 degrees around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.

What is the sequence of transformations for the image given? 

• Reflect over the x-axis, translate (x+8,y)

• Reflect over the x-axis then translate (x+6, y)

• Reflect over the y-axis then (x+1, y+1)

• Translate down 4 (y-4) and to the right 5 (x+5)

How would you differentiate between a line segment and a ray?

• A. By their angles

• B. By their lengths

• C. By their endpoints

• D. By their positions in space

Solene was tasked to create a model to represent a 90° angle, which of the following would be most appropriate?

• A. Drawing a curved line.

• B. Drawing two intersecting lines.

• C. Drawing a line with a single arrowhead.

• D. Drawing a straight line with two arrowheads.

How does the concept of an angle relate to the concept of a line?

• An angle is a subset of a line.

• An angle is always perpendicular to a line.

• An angle is formed by the intersection of two lines.

• An angle extends infinitely in both directions, similar to a line.
