1. GT Geometry Drill 10/6/14
1. Define a line of symmetry.
2. If I have point (x,y) and I reflect it
over the x-axis then use a vector
translation of <-4, 3> can you
write a rule to do the mapping in
one single translation?
2.
3. Warm Up
Determine the coordinates of the image
of P(4, –7) under each transformation.
1. a translation 3 units left and 1 unit up
(1, –6)
2. a rotation of 90° about the origin
(7, 4)
3. a reflection across the y-axis
(–4, –7)
4. Objective
• STW continue to work
with reflections and
translations to prepare
for the quiz!
