Translation are always _______

• Congruent
• Bigger
• Smaller
• Rotated

When you translate, (x-4,y) will move _____.

• 4 units right
• 4 units left
• 4 units up
• 4 units down

Identify the transformation from ABCD to A'B'C'D'.

• Translation
• Reflection across the y-axis
• Reflection across the x-axis
• 90^o counter clockwise Rotation

Point (-5,2) is reflected over the y axis.  Where is the new point located?

• (5,2)
• (-5,-2)
• (-5,2)
• (5,-2)

Apply the following rule to the point (-5,6):
(x,y)-->(y,-x)

• (-5,-6)
• (5,-6)
• (6,5)
• (-6,5)

If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, -5)
• (-5, 3)
• (-3, 3)

What are vertical angles?

• Angles that are adjacent to each other
• Angles that add up to 180°
• Angles that are opposite of each other when lines intersect
• Angles that add up to 90°
