Instruction- Vocabulary-Move Mathman to reveal definition
figure slides along a straight line without turningTranslation
the figure flips across a line of reflection, resulting in the mirror imageReflection
Rotationfigure turns around a fixed point
Translation- moving in a straight line without turning
Graph a triangle at A(-3,2)B(-5,2)C(-5,5)
Graph the translation of this triangle using the rule (x',y')=(x+2, y-4)
Reflection: Flip the image across a line to create a mirror image of the original
Graph an arrow
A(-4,1), B(-6,3) C(-5,6)D(-3,6), E(-2,3)
Reflect over the line y=-2
Rotation: the figure rotates around a fixed point
Rotate triangle ABC 180 degrees around the originA(-3,1)B(-7,1)C(-7,7)
