A plane figure that has one more side than a quadrilateral and one less than a hexagon is a... pentagon.
A quadrilateral has 4 sides anda hexagon has 6 sides. So the polygon between them is the one that has 5 sides. That is the pentagon.
A quadrilateral, pentagon or hexagon.
A quadrilateral has 4 sides (quad), in a in a simple figure, the 4 sides can make at most 4 angles, so no quadrilateral has more (or less, in actuality) than 4 interior angles. if the figure is a complex quadrilateral, edges can cross to make up to 6 interior angles, but since the complex quadrilateral must then be reducible into 2 triangles, it cannot have 6 right angles.
The answer depends on how the hexagon is partitioned.
A quadrilateral always has 4 sides... no more no less.
No. A hexagon can only have six sides. No more, no less.
Hexagon
It depends on what the angles are. If any of the angles have measurements greater than 180 degrees, it is concave. If all angles are less than 180 degrees, then it is concave. For example, a regular hexagon has six 120 degree angles, so it is convex. If there was a hexagon with five 90 degree angles and one 270 degree angle, it would be concave.
Triangle.
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.
Yes
It is a hexagon.
