Congruent

Two shapes are congruent if they are the exact same shape and size

3 angles in parallel lines

• alternate angles

• Corresponding angles

• Co-interior angles

Alternate angles

Are equal, called z angle, have same sides and occur of opposite sides of transversal

Angles in parallel lines

Angles created when 2 parallel lines are intersected by another line called a transversal

Transformation of shapes

• translate (3/4)

• Rotation, 180

• Enlargement, scale factor, Center of enlargement

• Reflection
