What is the name of a 2D closed figure that has straight lines (examples include rectangles, triangles, hexagons, etc.)

• rhombus

• polygon

• circle

• parallelogram

Check everything that is true about parallelograms...

• They are quadrilaterals

• Their area can be found by using:

  a = l x w

• Their height is measured by a perpendicular line from it's base to it's opposite side

• They have two acute and two obtuse angles

• Their base can be any of it's sides or the side it sits on

When dividing fractions we keep, (a)   , flip

When dividing decimals we can use the phrase, "If it's on the outside let it slide, if it's in the house - raise the roof". What does this mean?
