vertex
vertex
Point common to two sides of an angle = vertex. Points common to two sides of a polygon, if they exist, are all the points along an edge.
No polygon can have less than three sides.
the two sides of a polygon meet at the angle
An hexagon is a 2 dimensional polygon that has 6 sides
i you cant answer that, you must be in kindergarden. Anyway, a polygon is a 2-D figure with sides that do not intersect, are not curved, and all touch each other. A triangle is a type of polygon with...well...the root tri inplies it has three of something. the word angle says it has angles. so it has three angles. if it has three angles it has three sides. durr. /\ A triangle ==> / \ / \ --------
a polygon with 5 sides and 2 right angles is a pentagon
A polygon is a shape with 3 or more sides therefore a 2 sided shape isn't a polygon
A vertex of a polygon is where 2 sides meet
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
none. A triangle, in standard 2 dimensions cannot have any parallel sides. Let's show without going into formal proof. Let's say that you try to make a triangle with 2 parallel sides. -------------side a------------- |C | | |side b | | |A -------------side c--------------- Side a & b intersect at vertex C. Side b & c intersect at vertex A, and since sides a & c are parallel, they will never intersect, so there is no third vertex, so it's not a polygon, much less a triangle.
