Geometry Chapter 9 Transformations Test Review

The figure below shows ΔJKL on a coordinate plane. If ΔJKL is rotated 180° clockwise about the origin, what are the new coordinates of point K?

• (1, -2)

• (2, -1)

• (2, 1)

• (-1, -2)

The trapezoid is reflected about the line y = x. What is the location of the point L on the transformed trapezoid?

Jameson reflects this triangle across the x-axis to create ∆A'B'C'. What are the coordinates of A'?

• (2, -8)

• (8, -2)

• (-2, -8)

If ΔABC is translated 3 units down and 6 units to the left, write the coordinates of A'B'C'.

Triangle TRU has vertices T( -7,2)m R(2, -7), and U(8,0). It is dilated about the origin by a scale factor of 3 to obtain triangle T'R'U'. What are the coordinates of the vertices of triangle T'R'U'?

What is the x-coordinate of the image of the point (3, -2) under a dilation of 1.5 with the respect to the origin?

What is the y-coordinate of the image of point (-4, 2) under a dilation of 2 with respect to the origin?

What is the x-coordinate of the image of (-5, -4) when reflected in the y-axis?

What is the y-coordinate of R', the image of R(-9,8) after a reflection in the line y = x?
