Click on a Polygon to get started or click the name below
Quick Facts About Triangles
• A Triangle has 3 sides • A right triangle has 90 degree angle in
it• An acute triangle all of its sides are
no greater than 90 degrees• Obtuse triangles have one angle that
is greater than 90 degrees • A scalene triangle none of its sides
are equal• In an Isosceles Triangle at least 2 of
the sides are equal in length Return to Main Menu
Quick facts about the Square
• A square has 4 equal sides• All of the angles of the square are
equal• Since all of the angles and sides are
equal it can be referred to as a quadrilateral
• The area of the square is length * width
• The perimeter of the square is 4* the side
• A square is also a rectangle Return To Main Menu
Quick Facts About the Hexagon
• the Hexagon is a 6 sided polygon
• When all angles are equal and all sides are equal it is regular, otherwise it is irregular
• Soap bubbles tend to from hexagons
• The shape of the bee hives are also Hexagons
• The Perimeter of the Hexagon is the sum of all its sides
• Each of the six angles measures a total of 120 degrees
Return to Main Menu
Quick facts about the Octagon
• An Octagon has 8 sides • Its interior angles
measure 135 degrees• The Stop signs are in
the shape of an Octagon
• Octagons symbolize regeneration
• A regular Octagon has exterior angles that measure 45 degrees
• The total of all of the interior angles totals 1080

Quick Facts about the Rhombus
• A Rhombus is a flat shape
• Has 4 equal straight sides
• Opposite sides are parallel
• Opposite angles are equal
• The infield for baseball is in the shape of a rhombus
• All Rhombuses have 2 diagonals
Return to Main Menu
Quick facts about Rectangles • Opposite Sides are
parallel• All angles are right
angles • Opposite sides have
the same length • Adjacent sides are
perpendicular • Each rectangle
contains 2 diagonals• Each of the
diagonals intersect in halves

Quick facts about the Pentagon
• Has 5 sides • Exterior angles are
72 degrees • Interior angles
measure up to 108 degrees
• The sum of all of the inside angles totals 540 degrees
• There are no right angles
• A star has the form of a pentagon
Return to Main Menu
Quick facts about the Parallelogram
• Opposite sides are equal• Opposite angles are
equal• A Rectangle is a
Parallelogram• A Rhombus is also a
Parallelogram • A square is a
Parallelogram• The altitude (or height)
of a parallelogram is the perpendicular distance from the base to the opposite side
