AN OBJECT IS MOVED:
A TURN
A FLIP
A SLIDE
ROTATION = A TURN
REFLECTION = A FLIP

a cute little angle measures less than 90
ACUTE ANGLE
o
If the lines continued (crossed) you would say they are
INTERSECTING
OBTUSE ANGLE
a BIG FAT angle measures more than 90, but less than
180
oo
If the lines continued (crossed) you would say they are
INTERSECTING
RIGHT ANGLE
a right angle measures EXACTLY 90 o
If the lines continued (crossed) at 90 degrees; you would say they are
PERPENDICULAR
Parallel Lines
If the lines continued they would never intersect or cross~
think of the railroad tracks!
INTERSECTING LINES
Lines that continue (cross) FORMING ACUTE & OBTUSE
ANGLES
NO RIGHT ANGLES ARE
FORMED.acute

Perpendicular Lines
If the lines continue and cross forming
RIGHT ANGLESthen they are
PERPENDICULAR
