Set 44
- Rectangle.A frame is a quadrilateral with four 90-degree angles.
- Not a polygon.A grid is not a polygon because its lines intersect
at points that are not endpoints. - Not a polygon.Branches are open, and they “branch” out at
points that are also not endpoints. - Concave Dodecagon. A block letter is a closed multi-sided figure;
each of its line segments begin and end at an endpoint. A block
letter “M” will not have any curves and it will have 12 sides and
three interior angles that exceed 180°. - Triangle If the bread was square to begin, then it would be a right
isosceles triangle. If it was a rectangular slice of bread then it
would be a right scalene triangle. - Not a polygon. A balloon is either round or oval, but it does not
have straight sides with vertices. - Regular octagon.A stop sign is an 8-sided polygon with all sides
of equal length. - Not a polygon.Like the human face, lace is very intricate. Unlike
the human face, lace has lots of line segments that meet at lots of
different points.
Set 45
- Hexagon ABCDOE.As long as you list the vertices in
consecutive order, any one of these names will do: BCDOEA,
CDOEAB, DOEABC, OEABCD, EABCDO. Hexagon
ABCDOE is concave because the measurement of vertex O
exceeds 180°.
