What if a quadrilateral has no parallel lines?
A kite is a 4 sided quadrilateral that has no parallel sides
Is a square a polygon?
Yes
What is the opposite sides of a parallelogram are both parallel?
The opposite sides of a parallelogram are parallel lines and a parallelogram is a 4 sided quadrilateral
What is a quadrilateral that is not a polygon?
All 4 sided quadrilaterals are polygons but a square is the only 4 sided regular polygon.
What polygon has 4 sides 2 right angles and 1 set of parallel lines?
It would be a rectangle.
What is a 4 sided polygon with 2 pairs of parallel lines but NO lines of symmetry?
parallelogram
How many parallel sides does polygon have?
A 3-sided polygon has 0 parallel sides. A 4-sided polygon can have 0, 2 or 4 parallel sides. A 5-sided polygon can have 0, 2, 3 or 4 parallel sides. In general, an n-sided polygon can have 0, 2, 3, ..., n-1, or n parallel sides where n>5. A polygon with n sides can have n pairs of parallel sides (if n is even) or (n-1)/2 pairs if n is odd AND greater than 3. But it need not have any.
What is a 4 sided shape with no parallel lines?
quadrilateral
What if a quadrilateral has no parallel lines?
A kite is a 4 sided quadrilateral that has no parallel sides
What shape is 4 sided with two parallel lines?
paralellogram
What is a polygon with 1 sets of parallel lines called?
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
What shape is quadrilaterals?
A quadrilateral is a shape formed by 4 straight lines, a 4-sided polygon.
What shape has 4 sides and 2 parallel?
The four sided shape that has two parallel lines is called a trapezoid. A parallelogram is a four sided shape that has two pairs of parallel lines.
Is a square a polygon?
Yes
What are perpendicular and parallel lines on a polygon?
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
What is a four sided polygon with opposite sides parallel and congruent with 4 right angles?
A square or a rectangle
What is four-sided polygon 2 pairs of parallel sides 4 congruent sides?
Rhombus (or square).
