It depends on they type of arrowhead you have. If it is a arrowhead in the shape of a directional arrow, there are no obtuse angles. The most possible obtuse angles is 1.
It can do but that is not a requirement.
There are: 0.5*(10002-3000) = 498,500 diagonals
it's a 12 sided shape and it has 54 diagonals :D
A quadrilateral because it has 4 sides.
Only a chevron has diagonals intersecting outside the shape. The diagonals of a symmetric chevron will intersect at right angles.
A shape that contains at least two distinct intersecting lines is a figure called a cross. A cross consists of two lines that intersect perpendicularly at their midpoint.
A shape with non intersecting lines is 100 percent a parallelogram
Any quadrilateral (4-sided shape) has 2 diagonals.
Yes, the arrowhead shape is symmetrical along it's longitudinal axis (long side).
3
35 diagonals
An arrowhead
There are 54 diagonals in a 12 sided shape
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
An arrowhead can also be called a deltoid or a delta (either will do)!! hope this helps!!
A convex shape.
