Test Review for Transformations 8th Grade Pre-AP with Mr. G

Identify the missing coordinate given that there is a transformation Old coordiante New coordinate (3, 5) 5, 0 (4, 1) 6, -4 ? -2. -7

Translating the following figure 7 units down is the same thing as a reflection across what axis?

Write the translation rule for the following trapezoid if A is the original.

Triangle ABC is reflected and translated to form RQP Triangle ABC is reflected and translated to form RQP. Write the rule for the transformation

A triangle is translated left 5 units and up 2 units – then reflected across the y-axis. Write the rule for this transformation DO IT

A line segment has endpoints at (4, 4) and (-2, 7) A line segment has endpoints at (4, 4) and (-2, 7). It is reflected across the y-axis. Then it is translated up 2 units and down 3 units. Write the new coordinates.

Write the rule for the following transformation. Old triangle New triangle 4, -3 7, -17 14, 7 17, -7 -2, 5 1, -9

Which transformation does not preserve congruence?

Write the rule for the transformation from triangle ABC to A’B’C’ Write the rule for the transformation from triangle ABC to A’B’C’. Then write the transformation from ABC to A’’B’’C’’.

If the coordinate of a vertex of a polygon is located at (-3, -4) and the polygon is rotated 90 degrees, then reflected across the y-axis, and then translated 4 units up and 3 units to the right – what is the new coordinate of the vertex?
