How do we identify geometric shapes?
There are many different
polygonpolygon – a closed figure made up of three or more line segments.
Examples: The following are examples of polygons:
The figure below is not a polygon, since it is not a closed figure:
irregular polygon- a polygon that has sides of various lengths and angles.
parallelogramparallelogram- a shape that has four sides where the opposite sides are equal in length and parallel.
parallelogramparallelogram - a four-sided polygon with two pairs of parallel sides. The sum of the angles of a parallelogram is 360 degrees. Examples:
rhombus rhombus- a shape that has opposite sides parallel and four sides all of the same length.
rhombusrhombus -a four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees.
trapezoidtrapezoid – a four sided shape with only 2 parallel lines.
trapezoidtrapezoid - a four-sided polygon having exactly one pair of parallel sides. The two sides that are parallel are called the bases of the trapezoid. Examples:
rectangular prism – a three dimensional figure with 6 faces - opposite faces are the same size.
quadrilateralquadrilateral- a polygon with four sides and four angles.
90 x 4 =360 °
quadrilateral quadrilateral - a four-sided polygon. The sum of the angles of a quadrilateral is 360 degrees. Examples:

How many ways can we measure things?
Ways to Measure Length
• Inch •Feet•Yard•Meter•Centimeter
lengthlength -the longest measure of anything. A ruler helps you measure length.
inchinch- a measure of length equal to 1/12 of a foot. A way to measure length. A quarter is about 1 inch.
12 inches = 1 foot
footfoot- 12 inches equals 1 foot. Use a ruler to measure length.
12 inches = 1 foot
yard yard- a unit of measure of 3 feet or 36 inches. Use a yard stick to measure length.
36 inches = 3 feet = 1 yard
centimetercentimeter – Metric Measurement - A unit which is less than an inch or 1/100 of a meter. A way to measure length.
metermeter – the basic unit of length in the MetricSystem which equals about 39 ½ inches. Meter –a way to measure length.
