a arrowhead has got 4 sides all of them do if u dont belive me go on arrow heads and count the sides
A polygon can have any whole number of sides more than 2.
A pentagon has got 5 sides ,a hexagon has got 6 side's octagon has got 8 sides.
A hexagon has 6 sides.
A triangle has got 3 sides to it & that's why it's called a triangle. Three sides.
yes an arrowhead has 4sides because it is a quadrilateral but it doesn't have any parallel sides
a arrowhead has got 4 sides all of them do if u dont belive me go on arrow heads and count the sides
No but its diagonals are perpendicular
it has got two pairs of adjacent sides of equal length and one pair of equal sides
Yes,I think it has got one
Yes. By definition a square has four equal sides and four 90º angles, so any two adjacent sides are perpendicular.
Yes. The two angles on either side of the reflex angle are normally equal.
An Arrowhead has got 1 line of symmetry so do NOT beleive what anyone else says!
No but it has perpendicular lines that meet at right angles.
It can - up to 6 pairs of parallel sides.
Any "irregular" polygon.
Yes, a square by definition has four sides that are all equal in length and four right angles. These sides are perpendicular to each other, meaning they form 90-degree angles at the corners. Therefore, a square does have vertical sides as they stand perpendicular to the ground or any horizontal plane.
