Geometry 1.1 Review

A plane has all the following properties:

• A length

• A width

• A height

• Infinite (or goes on forever)

• Can be represented by a flat surface

The difference between a line and a segment is: a line is ______ and a segment is ______

• Infinite; a piece of a line with endpoints

• 2 dimensional; 1 dimensional

• measurable with a ruler; infinite

• named by the points on the line; named like people are (Tom or Jeff)

Which of the following are rigid transformations?

• Translations

• Reflections

• Rotations

• Dilations

Rigid Transformations always preserve which two parts of a figure?

• Location of a figure

• Distances of a figure

• Nature of a figure

• Angles of a figure

What is the scale factor that can be used to dilate  $\Delta ABC$  to create  $\Delta A'B'C'$  

• 2

• 4

• 3

• 1/2

A midpoint of a segment is defined as...

• A point that falls anywhere in the middle of two other points

• A point that divides a segment into 2 exactly equal pieces

• A point that is just kind of meh

• A point at (0, 0) on a coordinate grid

Would point C be considered the midpoint of Segment AB?

• Yes, it is in between the two

• Yes, AC = CB

• No, because AC=1 and CB=5

• No, because B is the midpoint

Points L, M, and N are collinear. N lies between L and M.

LM= 5x+1

LN= -x+27

MN= 3x-8

What is the value of x?

A translation is ______ a figure

• Turning

• Sliding

• Flipping

• Shrinking or Enlarging

A reflection is _______ a figure

• Turning

• Sliding

• Flipping

• Shrinking or Enlarging
