What is concave hexagon?
It is a hexagon with a reflex angle.
A arrowhead is a concave polygon as it has a what angle?
Reflex angle
What is the definition of concave hexagon?
A concave hexagon is a hexagon that has one or two reflex angles. With one reflex angle, it will resemble a chevron - like a stripe on a police or army uniform, or the letter V which has thickness. With two reflex angles, it will resemble an hourglass with straight sides.
What is a irregular five sided shape with one reflex angle?
A concave pentagon.
Can quadrilaterals have reflex angles?
Yes, it looks like an arrowhead and is called a concave quadrilateral.
Could a concave quadrilateral have more than one reflex angle?
A reflex angle is over 180 degrees, but the sum of the angles in a quadrilateral, concave or convex, is 360. Therefore, since 180+180=360, you can't have any more degrees even without the amount over 180 that the reflex angle has.
Which shape has one reflex angle?
Any concave polygon. It must have at least 4 sides.
Why is the patellar reflex called a somatic reflex?
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
What does a cocave hexagon look like with diagnals?

How can you determine if a polygon is concave?
It must have at least one internal angle which is a reflex angle - that is, between 180 and 360 degrees.
What is a concave m polygon?
A concave m polygon is a 2-dimensional shape which is bounded by m straight sides with at least one internal angle that is a reflex angle (greater than 180 deg).
How does concave graph look like?
Many graphs that appear concave from one side will appear convex from the other. A smooth graph is generally described as concave if it is increasing AND if the rate of increase is also increasing. In terms of calculus this requires the first and second derivative to be positive. A concave polygon is one in which at least one of the vertices forms a reflex angle.
