How many parallel sides does an equilateral triangle have?
none, the three sides meet so there are no parallel sides but all the sides are equal.
How many parallel sides does a nonagon have?
A nonagon can have none, or anything up to four pairs of parallel sides. You can even have two quartets of parallel sides in you allow concave nonagons.
How many parallel lines does an oval have?
An example of parallel lines are the two rails of a railway track, rails which never meet. An oval is a line or shape that has no parallel lines.
How many pairs of parallel sides does a regular heptagon have?
Ah, a regular heptagon is a special shape with seven sides. Each pair of opposite sides in a regular heptagon are parallel, so it has three pairs of parallel sides. Just imagine those lovely sides stretching out peacefully and evenly, creating a harmonious shape.
What has 4 sides but sides aren't all the same?
If all the sides are different lengths, it can only be called a quadrilateral. In general, four sided two dimensional objects are called quadrilaterals. When all four sides are the same length it is a square if all four corners are right angles. Otherwise it is a rhombus. If the opposite sides are the same length, it is a rectangle if the four corners are right angles, otherwise it is a parallelogram. In all these cases, the opposite sides are parallel to each other. There is also the trapezoid, a quadrilateral with only one pair of parallel sides. If the opposite sides are the same length but not parallel. it is an isosceles trapezoid.
