1-5 Activity #1
1.) Reflect over the y-axis.
The pre-image was A(-6,0) B(2,4) and C(-2,-2). Identify the coordinates of the image.
What is the general coordinate rule for a reflection over the y-axis?
2.) Rotate 90 degrees counterclockwise.
The pre-image was A(0,3) B(1,2) and C(4,3). Identify the coordinates of the image.
What is the general coordinate rule for a rotation 90 degrees counterclockwise?
3.) Translate right 5 units and up 2 units.
The pre-image was A(-4,-2) B(-3,2) and C(-2,-2). Identify the coordinates of the image.
What is the general coordinate rule for translating a figure right a units and up b units?
4.) Reflect over the y=x line.
The pre-image was A(-4,2) B(0,6) and C(-4,-2). Identify the coordinates of the image.
What is the general coordinate rule for reflecting across the y=x line?
5.) Rotate 180 degrees.
The pre-image was A(-4,-2) B(-3,2) and C(-2,-2). Identify the coordinates of the image.
What is the general coordinate rule for rotating 180 degrees?
