If the red triangle is rotated 180 degrees, then reflected over y=2 what is the final image?

• Green Triangle

• Blue Triangle

• Orange Triangle

• Red Triangle

What is the transformation from Triangle ABC to Triangle A''B''C''?

• Reflection x-axis, then rotation of 180 Degrees

• Reflection over y-axis, then rotation of 90 Degrees

• Rotation of 90 Degrees, then reflection over x-axis

• Rotation of 180 Degrees, then reflection over y-axis

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the y-axis

• Reflection across the x-axis

The coordinates of triangle JRB  are ,J(1, -2) , R(-3, 6) and B(4, 5) .  What are the coordinates of the vertices of its image after the transformation T_{2, -1} o r_y-axis ?

• (3, 1), (-1, -7), (6, -6)

• (3, -3), (-1, 5), (6, 4)

• (1, -3), (5, 5), (-2, 4)

• (-1, -2), (3, 6), (-4, 5)

If the coordinates of point P are (2, -3) , then R₉₀ o R₁₈₀ is

• (-2, 3)

• (-2, -3)

• (3, -2)

• (-3, -2)

Describe the transformations that map ABC onto A"B"C"

• translate 5 up and 1 left then reflect over y

• translate 5 down and 1 left, then reflect over y

• reflect over y=x then translate left 8

• reflect over x then rotate 90 clockwise

Which of the following describes the sequence of transformations shown?

• Rotate -90 degrees around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.

Triangle XYZ has vertices X(-2, 2) Y(3, 2) and Z(-5, -6). Rotate the figure 180 degrees, translate it 2 units up and 4 units right, then dilate by a scale factor of 2. What are the new coordinates?

• X'''(8,4) Y'''(-2,4) Z'''(14,20)

• X'''(12,0) Y'''(2,0) Z'''(18,16)

• X'''(12,0) Y'''(2,0) Z'''(3, 4)

• X'''(8,4) Y'''(2,0) Z'''(14,20)

Find the image of A( -3, 5) after translating (x,y) --> (x , y-4) then reflecting across the y-axis

• (3,1)
