They are equal line segments that meet at an angle of 135°.
Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).
A square, a rectangle, a quadrilateral, or a trapezoid. (there's more, but I won't bore you)
If each segment intersects exactly two other segment but could, if extended, intersect the third, then the figure is a quadrilateral. Otherwise it is a parallelogram.
frequency polygon
No, it can only have one midpoint, because if it had two midpoints, then there would be two line segments! Also, if you add two midpoints, then thus creating another segment.
not in euclidean geometry (I don't know about non-euclidean).
whats a quadrilateral with 2 sides not parallel and 2 sides parallel
The Centroid is the point that is created when the midpoints of each side are connected with a straight line to the opposite vertex, or corner.Centroid Facts:Always inside the triangle.Each side of the triangle is divided into two equal segments.
A quadrilateral has 4 line segments

A quadrilateral.
No, because if there is more than one midpoint then it will be like multiple line segments connected together. You can't have two midpoints or more, but you can have one to divide the line segment in half.
There are 4
Four line segments can always form a quadrilateral, as long as none of them is longer than the sum of the lengths of the other three,
non adjacent
