The collaborative activity
Connect the shape cards with the word cards.
Initial assessment task
1.
Draw the shaded triangle after:
a)
it has been translated 7
units horizontally and +1 units
vertically. Label your answer
A
.
b)
it has been reﬂected in the
x
axis. Label your answer
B
.
c)
it has been rotated 90°
clockwise about (0,0). Label
your answer
C
.
d)
it has been reﬂected in the
line
y = x
. Label your answer
D
.
2.
Describe fully the single transformation that:
a)
takes the shaded triangle onto the triangle labeled
E
.
b)
takes the shaded triangle onto the triangle labeled
F
.
3.
Describe a single transformation that has the same effect as rotating
a shape 90°clockwise, then reﬂecting the result in the
axis.
