Trevor rotated the triangle 90° counterclockwise
about the origin to create figure 𝑇′𝑉′𝐸′. What
are the coordinates of the vertices of figure
𝑇′𝑉′𝐸′ after the rotation?
They were told to
translate the
parallelogram: (𝑥, 𝑦) →
(𝑥 + 6, 𝑦 + 1)
(parallelogram 𝑃′𝑄′𝑅′𝑆′)
and then reflect it over
the 𝑥 – axis, and label the
new parallelogram:
𝑃′′𝑄′′𝑅′′𝑆′′.

The point (−6, 14) is a vertex of a
trapezoid. When the trapezoid is reflected
over the 𝑥 – axis, what are coordinates of
the image of the vertex?
A transformation maps a pre-image triangle to the
image triangle shown in the coordinate plane below. If
the pre-image triangle is reflected over the 𝑦 – axis to
get the image triangle, what are the coordinates of the
vertices of the pre-image triangle?
The transformation below maps triangle 𝐻𝐽𝑋
onto triangle 𝐻′𝐽′𝑋′ using a rotation. Are the
pre-image and image congruent? Explain your
reasoning.
Trapezoid 𝐼𝐽𝑅𝑇 is shown in the coordinate plane below.
Trapezoid 𝐴𝐵𝐶𝐷 (NOT SHOWN) has coordinates
𝐴 −5, 2 , 𝐵 −5, 3 , 𝐶 −4, 4 , 𝐷(−3, 4). Determine
whether or not trapezoid 𝐼𝐽𝑅𝑇 is congruent to
trapezoid 𝐴𝐵𝐶𝐷.
