AREA = SURFACE L X W PERIMETER = DISTANCE AROUND P=s+s+s+s
7
DEPTH = HOW DEEP
8
D I A M E T E R DIAMETER = DISTANCE ACROSS A SPHERE OR CIRCLE
9
RADIUS RADIUS = ½ DISTANCE ACROSS A SPHERE OR CIRCLE CIRCUMFERENCE = THE DISTANCE AROUND A SPHERE OR CIRCLE

FRACTIONS = PARTS OF A WHOLE

TRANSFORMATIONS TRANSFORMATIONS ARE THE WAY AN OBJECT IS MOVED: A TURN A FLIP A SLIDE
14
ROTATION = A TURN
15
REFLECTION = A FLIP

27
a cute little angle measures less than 90 ACUTE ANGLE o If the lines continued (crossed) you would say they are INTERSECTING
28
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
29
RIGHT ANGLE a right angle measures EXACTLY 90 o If the lines continued (crossed) at 90 degrees; you would say they are PERPENDICULAR
30
Parallel Lines If the lines continued they would never intersect or cross~ think of the railroad tracks!
31
INTERSECTING LINES Lines that continue (cross) FORMING ACUTE & OBTUSE ANGLES NO RIGHT ANGLES ARE FORMED. acute obtuse
32
Perpendicular Lines If the lines continue and cross forming RIGHT ANGLES then they are PERPENDICULAR
