Reflection

What kind of transformation is this?

Rotation

How did the triangle move?

Rotated 90 degrees clockwise

What is a rotation?

When a figure turns or rotates.

How can I get triangle A to triangle C in two movements?

2 counterclockwise rotations by 90 degrees

What is a translation?

When you slide a figure

What kind of transformation is this?

A rotation

What kind of transformation is this? How did it go through the transformation?

Reflection over the x-axis.

How did the blue triangle translate to the red triangle?

5 units right, 3 units down.

What is a reflection?

When you flip an image

How can I move from triangle C to A in just 1 move?

A reflection

What two directions can you rotate?

Clockwise and Counterclockwise

How can I get from triangle PMT to triangle XYZ?

Reflect over x-axis then translate 10 units to the left.

If we reflected this over the x-axis, what would be the new coordinates of point b be?

(3,-2)

What would to coordinates of the point be after a translation left 6 units and down 4?

(-5,0)

What transformation do we use to go from the orange triangle to triangle s?

A reflection over the y-axis.

The points (-4, 8) is dilated by a scale factor of 5. What is the new point?

(-20, 40)

The purple triangle was dilated and resulted in the green triangle. What is the scale factor?

2

The point (-5, 6) is rotated 90˚ clockwise about the origin. What are the coordinates of the new point?

(6,5)

The point (-6, 8) is dilated by a scale factor of 2/3. What are the coordinates of the new point?

(-4, 16/3)

Which transformation results in a similar figure (not a congruent one)?

translation

dilation

rotation

reflection

A triangle is dilated with a scale factor of "x". If one of the vertices was at (-7, -2), which ordered pair represents the vertex after the dilation?

(-7 - x, -2 - x)

(-7 + x, -2 + x)

(-7/x, -2/x)

(-7x, -2x)

What 2 transformation occurred to move the blue triangle to the brown triangle?

Reflection (over the x-axis), Translation (5 left)

Are the blue and the pink triangle similar or congruent?

congruent

Choose the correct answer

D

When you reflect across the y-axis, which coordinate do you not change: x or y?

y

A figure is translated 8 units left and 2 units up. Write the rule.

(x - 8, y + 2)

Which rule was used to change ∆ABC to ∆A'B'C'?

(3x, 3y)

(x+3, y+3)

(x-3, y-3)

(1/3 x, 1/3 y)

If the scale factor is greater than 1, will the new figure be bigger or smaller than the original?

bigger

A square is rotated 180˚ about the origin. If one of the vertices was at (4,5), where will the new vertex be after the rotation?

(-4,-5)
