Polygons
* Four sided figures
*closed figures made by line segments
RegularPolygons
* Four sided figures
*closed figures made by line segments*all segments and all angles are equal
IrregularPolygons
* Four sided figures
*closed figures made by line segments*segments and angles are not necessarily equal
Polygon SortIs that shape a polygon?
Drag each shape onto the word, "polygon".If it is a polygon, it will disappear.
If it is not a polygon, it will stay visible.
Polygon
Quadrilaterals* four sided polygon
*measures of the angles add up to 360°
Quadrilateral
Quadrilateral SortIs that shape a quadrilateral?
Drag each shape onto the word, "quadrilateral".If it is a quadrilateral, it will disappear.
If it is not a quadrilateral, it will stay visible.
Rhombus*four-sided polygon with all sides
equal lengths *measures of the angles add up to
360°
Parallelogram*four sided polygon
*two pairs of parallel sides*measures of the angles add up to 360°
Rectangle*four sided polygon
*two pairs of equal sides*four 90° angles
*measures of the angles add up to 360°
Square*four sided polygon*all sides are equal*all angles are 90°*measures of the angles add up to 360°
Trapezoid*four sided polygon*exactly one pair of parallel sides
Using multiple pattern blocks, how many triangles, quadrilaterals, pentagons, and ...... can you make?
In a rhombus, all sides are equal.In a parallelogram, only pairs of sides are equal.
They both have:4 sides

Congruent -or-
Similar?
Congruent*the same shape and size*two shapes are congruent if you can turn, flip and/or slide one so it fits exactly on the other
Similar*the same shape, but NOT the same size

Flips, Slides, -and-Turns
Flips
*a transformation in which a plane figure is flipped or reflected across a line, creating a mirror image of the original figure
FlipsMake a flip using a picture of yourself on Picnik.com.
Use the "flip" feature in the edit menu to make the flip.
Slides*move a shape without rotating or flipping it
*the shape still looks exactly the same, just in a different place
Slides
Make a slide using a picture of yourself on Picnik.com.Use the "collage" feature in the to make the slide.
Turns
Make a turn using a picture of yourself on Picnik.com.Use the "rotate" feature in the edit menu to make the turn.
