Size

The relative extent of something; how big something is www.enchantedlearning.com/subjects/.../**activities**/**math**/**size**.shtml **(jdp)**
 * Size**:

[|Measurement], the process or the result of determining the magnitude of a quantity, such as length or mass, relative to a unit of measurement, such as a meter or a kilogram (jpd) [] (jdp)

Size - Measure

[|Perimeter]- total distance around the outside of a 2D shape. (mkm)

Point- A point specifies only location; it has no length, width, or depth. We usually represent a point with a dot on paper, but the dot we make has some dimension, while a true point has dimension 0.

__Area__- the amount of space inside a flat 2D shape or boundary like a rectangle, triangle, or circle. (JMG) Area of a rectangle = base x height Area of a triangle = ½ base x height Area of a circle = ** π ** r 2

__[|Volume]__: the amount of space, measured in cubic units, that an object or substance occupies. (MLS


 * Circumference of a Circle (fdy) **

The distance around a circle. It is equal to Pi times the diameter of the circle. Pi or is a number that is approximately 3.14159.

[|Angle] - the amount of turn between two straight lines that have a common end point (hld)

[|Arc] An arc of a circle is a segment of the circumference of the circle. They have length as a portion of the circumference, but they also have a measurable curvature, based upon the corresponding central angle. (JRP)

[|End point] A point (usually represented by a dot) that shows where a line segment begins or ends. (rec)

[|Surface Area]- the total area each face of a three-dimensional object takes up. The surface area can be found by finding the area of each face, then added all face areas together. (mnj)

[|Altitude] - is a distance measure, typically refers to the height of a shape from its base to the top most vertex (JLH)

Compression Contraction- a transformation in which a figure grows smaller (JPL)

[]

Congruent - Exactly equal in size and shape. [] (rj)


 * Ruler -** a straight piece of material that is used for measuring distances or drawing straight lines. http://www.enchantedlearning.com/dictionarysubjects/measurement.shtml (jpb)
