Transformations and Tessellations

The three properties of tessellations

• Enlargement

• Rotating

• Stretching

• Reflection

• Translation

Does the image tessellate?

• Yes

• No

Which of these four shapes does NOT tessellate?

• Regular Hexagon

• Regular Pentagon

• Square

• Equilateral Triangle

Triangle ABC is going to be translated. Where would A' position be if the translation is 3 units right and 2 units down?

• (3,3)

• (5,3)

• (5,9)

• (1,4)

Write a rule for the translation:

• (x+2, y+1)

• (x+2, y+4)

• (x+4, y-3)

• (x+2, y-1)

A type of translation where a geometric figure slides horizontally, vertically, or both. What type of transformation is this?

• No Translation

• Rotation

• Reflection

• Translation

Write the rule for this translation: Slide 3 up and 2 right.

• (x, y) ----> (x+1, y-5)

• (x, y) ----> (x-2, y-6)

• (x, y) ----> (x-2, y+4)

• (x, y) ----> (x+2, y+3)

What information do you need to make a reflection?

• Type of Reflection

• Line of Reflection

• Distance of Reflection

• Direction of Reflection

When the Ferris wheel is in motion, what geometric transformation is each seat performing?

• Translation

• Rotation

• Reflection

• Tessellation

If P = (-5, 2) and P' = (5, -2), what transformation was performed on P?

• Rotation about the origin 180 degrees

• Rotation about the origin 270 degrees

• Reflection over the x-axis

• Reflection over the y-axis
