### perpendicular

lines that intercept to form a right angle

### congruent

figures that have the same sides and shape.

### transformation

a mapping of a geometric figure that may change its shape or position

### alternate exterior angle

they are on opposite side of the transveral and outside the parallel lines

### interior angle

lie inside the parallel line

### exterior angle

lie outside the parallel line

### corresponding angle

in the same position on parallel in relationship to the transveral
