Area & Perimeter
The way to solve for area
Multiply: length x width
lines that never touch
parallel
shape with 4 sides
quadrilateral
0 faces, 0 edges, 0 vertices
sphere
2 ways that a pattern grows
Addition, multiplication
The way to solve for perimeter
Add: side + side + side... etc
set of points in a straight path that extends in opposite directions without ending
line
Means the same
(same length, same angle, etc)
congruent
6 faces, 8 vertices, 12 edges
(there's 2)
cube, rectangular prism
2 ways that a pattern shrinks
subtraction, division
Rectangle: length is 5 in, width is 4 in
What is the perimeter?
18 in
exact position on a plane surface
point
shape with 2 pairs of parallel sides
(there's 4)
rhombus, parallelogram, rectangle, square
2 faces, 0 edges, 0 vertices
cylinder
What type of pattern, what rule:
0, 5, 10, 15, 20, 25
growing, +5
3 sided polygon. Each side is 9 m.
What is the shape? What is the perimeter?
triangle; 27 m
part of a line that has one end point and extends in one direction without ending
ray
plane figure with 1 pair of parallel lines
trapezoid
How are a cube and a rectangular prism...
>the same?
>different?
Same: # of edges, faces, vertices
Different: shape of faces; cubes have the same face
What pattern, what rule:
48, 24, 12, 6, 3
shrinking; divide by 2, split in half
4 congruent sides; side is 2 cm
What's the shape? What's the area?
rhombus, square; 4 cm2
lines that cross at 90ยบ
perpendicular
A place figure that is NOT a polygon nor a quadrilateral
circle
5 faces, 5 vertices, 8 edges
square pyramid
What pattern, what rule:
2, 7, 5, 10, 8, 13, 11, 16, 14
alternating, +5 -2
