Move one corner the right number of dots, then every other corner the same way, and join them. For a turn, turn each corner around the big dot like a clock hand.
slide (translation)move without turning or flipping
turn (rotation)spin around a point
clockwisethe way a clock's hands go
congruentsame shape and same size
Watch for: Moving some corners further than others, so the shape stretches. Turning counterclockwise instead of clockwise. Calling two shapes congruent when one is longer.
At home: Trace a cut-out shape, slide it along a table edge and trace it again. Then turn it and trace once more: is it still the same shape?
