Polygons Grade 6 Geometry What is a Polygon????

Polygons Grade 6 Geometry What is a Polygon???? . A polygon is a closed plane figure with 3 or more sides, it must have all straight lines, no curves

Look around the room, with a partner, make a list of polygons in the classroom. Classifying Polygons by # of Sides 3 sided Polygon Triangl = e Hint: Think Tricycle,

tripod, Trilateration (Tri means 3) Classifying Polygons by # of Sides 4 sided Polygon Quadrilateral = Hint: Think Quadrant, Quadruple, Quad (AKA 4-Wheeler)

Classifying Polygons by # of Sides 5 sided Polygon Pentagon = Hint: Think Pentathalon, or the government building The Pentagon

Classifying Polygons by # of Sides 6 sided Polygon Hexagon = Hint: Both Hexagon and Six have an x in them Classifying Polygons by # of Sides 7 sided Polygon Heptagon

= Can you come up with a hint for remember a heptagon? Classifying Polygons by # of Sides 8 sided Polygon Octagon = Hint: octopus 8 legs

Classifying Polygons by # of Sides 9 sided Polygon Nonagon = Hint: Non is similar to Nine Classifying Polygons by # of Sides 10 sided Polygon Decagon

= Hint: Think Decade (10 years Classifying Polygons by # of Sides # of Sides Name

3 Triangle 4 Quadrilateral 5

Pentagon 6 Hexagon 7

Heptagon 8 Octagon 9 Nonagon

10 Decagon Two Types of Polygons Convex all vertices point outward Concave at least one vertex points inward towards the center of the

polygon (The side looks like it caved in) Regular Polygons A Regular Polygon is a polygon in which all sides are the same length. Equilateral Triangle

Square Review of Similar Triangles 2 Triangles are similar if they have the same shape (i.e. the same angle in the same positions) Similar Polygons The same is true of polygons. 2 polygons are similar if they have the same angles in the same

positions (i.e. same shape) Similar Trapezoids ^ Similar Pentagons ^ Similar Rectangles Parallel Sides

Reflex Angle Parallel Sides: Two lines on a plane that never meet. They are always the same distance apart. Reflex Angle: An angle that is greater than 180 degrees On chart paper, draw a large Venn diagram with

loops. Decide how you will label each loop. Choose from these attributes: Regular Quadrilateral Parallel Sides Irregular Pentagon Equal Sides Triangle

Hexagon Reflex Angle Acute Angle Right Angle Obtuse Angle Using the shapes provided, trace them into their appropriate

categories
