Chapter 9 Geometry

What are Transformation

• Translation

• Rotation

• Reflection

• All answers

Point X is located at (4,1) and a translation occurs at (x+3,y+1) and followed by a reflection over y =1 where are the coordinates if X'

• (7,0)

• (0,7)

• (-1,7)

• (1,7)

Point A is located at (3,4) if a double reflection take place on x=2 and x= 4 how far is S' located to S

• 4 units

• 6 units

• 8 units

• 12 units

What is symmetry

• When two or more parts of as shape are Identical after a flip, slide or turn.

• When a shape moves location nothing else.

• The shape changes sizes.

How many lines of symmetry does this shape have

• 2

• 1

• 4

How many lines of symmetry does this shape have

• 1

• 2

• 3

What do dilations do?

• The produce the same shape but different size

• Don't change size just location

• Rotates the shape around a center point

If Z is the centroid, what type of segments are drawn?

• angle bisectors

• perpendicular bisectors

• altitudes

• medians

CF, BE, and AD are the medians of the triangle. If BF =10, find AF.

• 20

• 10

• 5

• Not Enough Information

X is the centroid of the triangle. If ZX = 3, find AZ.
