How Many Sides?
I am a special kind of parallelogram that has 4 right angles but my sides are not always equilateral.
What is a rectangle
What are the 3 attributes a shape must have in order to be classified as a polygon?
Only straight edges/sides - No curves
No gaps - Closed figure
No overlaps - No crisscrossing lines
I am the features or characteristics of a shape.
What are attributes?
What is the difference between a regular and nonregular polygon?
A regular polygon has all sides of equal length and all interior angles of equal measure. An irregular polygon, on the other hand, does not have all sides equal and all angles equal.
a triangle with a 90 degree angle
What is a right triangle.
a quadrilateral with 4 equal sides but only sometimes has 4 right angles.
What is a rhombus
What is the difference in a convex and a concave polygon?
Convex- All angles "flex" out
Concave- At least one angle "caves" in
How are triangles classified?
By angles and side lengths
Draw the quadrilateral hierarchy
Quadrilateral
Parallelogram Trapezoid
Rectangle Rhombus
Square
I am any flat, closed shape with straight sides that do not overlap.
What is a polygon
Draw a diagram to show the hierarchy of the following categories.
Rectangles, triangles, squares, polygons, parallelograms, quadrilaterals, equilateral triangle, isosceles triangle
Polygons
Quadrilaterals Triangles
Parallelograms Isosceles Triangle
Rectangles Equilateral Triangle
Square
