STRETCHES AND SHEARS

Which is which? WHICH IS A STRETCH OF THE RED SQUARE? WHICH IS A SHEAR OF THE RED SQUARE?

STRETCH WHICH IS THE INVARIANT LINE? THE STRETCH IS PARALLEL TO…..? WHAT IS THE SCALE FACTOR?

DIFFERENCE BETWEEN STRETCH AND SHEAR NOTICE THE ANGLES NOTICE THE SHAPE WHAT IS THE DIFFERENCE BETWEEN THE TWO IMAGES OF THE UNIT SQUARE ( THE BLUE IMAGE AND THE GREEN IMAGE)?

PLOT THE FOLLOWING POINTS

SHEAR

PLOT THE FOLLOWING POINTS

IMPORTANT STRETCH SCALE FACTORfrom invariant line = distance moved by a point divided by the distance of the shape

IMPORTANT SHEAR SCALE FACTOR
