5. EDGES FACES VERTICES

6. 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

13. 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
