Students learn that a rotation of 180 degrees moves a point on the coordinate plane , (a,b) to (-a,-b).
Students learn that a rotation of 180 degrees around a point, not on the line, produces a line parallel to the given line.
Here is a highlight reel of some of the greatest 180 degree slam dunks! Remember that 180 degree rotation is turning half way around.
We now have definitions for all three rigid motions: translations, reflections, and rotations.
We now know that a 90 degree rotation will transform the object.
REMEMBER: Rotating an object a positive amount of degrees is a counter-clockwise motion.
Rotating an object a negative amount of degrees is a clockwise motion.
This is a printable blank version of Lesson 5 for Module 2 8th grade math.
We are now graduating from using tracing paper to view a rotation, and learning how to rotate a figure any amount of degrees by using a protractor and a ruler.
Rotations of degrees are special:
(Collinear means that the points all can be connected with one straight line)
