Its a circle.
Lots of possibilities: an isosceles triangle, an isosceles trapezium, an irregular polygon with an odd number of sides, where the sides and angles on either side of the base are symmetric.
A line does not in itself have any sides. One could however say that if you had to choose which side of a line to be on, then there are multiple answers:If the line is in one dimensional space, then it encompasses everything and you have zero sides to choose from.If the line is in two dimensional space, then you can be on one of two sides of that line.If the line is in three dimensional space, then there are an infinite number of sides to choose from.
one.
Yes. A line segment has one dimension. There are lots of one-dimension shapes. like a ray, line segment and line.
Lots of figures don't.
A oval has no sides, like a circle it has just one continious line :)
a trapazoid
A pentagon
A pentagon
A ray has one arrow on the right. A line segment has a dot on both sides. A line has a arrow on both sides.
Trapezoid
Yes, it has sides that are straight line segments. Exactly one pair of opposite sides is parallel. Polygons do not have curved sides.
