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
Angular Momentum (L). Rotational equivalent of linear momentum. Product of a body's moment of inertia and its angular velocity. Vector quantity (use right-hand rule: curve fingers in direction of rotation, thumb points in vector direction of L)
Von Thunen's Theories of Land Use and Agricultural Organization How is agricultural land organized? How does this impact the cost of rent/purchasing land? Land Use and Agriculture Terms Fallow - the practice of farming land, harvesting, tilling (but not planting),...
Radians per second is the SI unit for angular speed. The lower-case Greek letter tau is the symbol used for torque. Torque is measured in units of distance times a force, like pound-inches, or newton-meters. Newton-meters is the SI unit...
If the compound noun is formed in one word, the plural is formed by adding either "s" or "es," based on the rules described earlier. Example: Mouthful Mouthfuls. If the compound noun is formed with more than one hyphenated word,...
