- Discussion Questions
Before Video
Is a circle a polygon? Why or why not? ANSWERIt is not. A polygon is a closed shape that has straight sides, while a circle has curves.
Squares and rectangles.
Any drawing of a closed shape with exactly 5 sides.
Four.
A triangle.
After Video
What is one shared attribute of squares and rhombuses?ANSWERBoth have all sides equal in length. Both have two sets of parallel sides.
Squares have four right angles and rhombuses do not.
Both belong to parallelograms, quadrilaterals, and polygons.
The number gets smaller since the new category is more specific.
Squares fit ALL of the attributes that define rectangles, but rectangles do not fit all of the attributes that define squares. Not all rectangles have four sides of equal length.
