Technically, a rhombus is a parallelogram, but a parallelogram is not always a rhombus. A parallelogram is any four-sided shape with two sets of parallel lines. A rhombus is a parallelogram with all equivalent side lengths. So, a rhombus is a more specific parallelogram. (And so is a a square or a rectangle.)
A quadrilateral is "guaranteed" to be a parallelogram if (a) the opposite side are parallel, or (b) any line segment perpendicular to one side and intersecting the opposite side is also perpendicular to the opposite side, or (c) any line segment perpendicular to one side and intersecting the opposite side has the same length as any other such perpendicular line intersecting the opposite side (sometimes vaguely expressed as "opposite sides are everywhere equidistant"), or (d) the angles at the two ends of any side add up to 180 degrees.
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
A parallelogram that is not a square is any parallelogram whose angles are not ninety degrees or whose opposite sides are not equal.
The diagonals are not congruent unless the parallelogram happens to be a rectangle.
A straight line of finite length can be a side in a parallelogram.
the base :)
It is a straight line segment.
Is rectangle and any parallelogram not square or rhombus
A parallelogram is a 4 sided quadrilateral and has 2 pairs of opposite parallel sides
Assuming that you are asking about the formula for the AREA of a parallelogram (there is no formula for a parallelogram), A = bh where A is the "area", b is the length of any side (called a "base"), and h is the "height" measured perpendicular from that base to the opposite side.
If you pick any side of a parallelogram, there's always another side parallel to it. With a trapezoid, that's true for two of its sides, but not for the other two.
yes, as long as 2 sides are parallel, its a parallelogram.

Area circle: π × radius² Area triangle: ½ × base × height Area Parallelogram: base × height Area: Rectangle: length × width In a triangle, the base is any side between two vertices and the height is the perpendicular distance from this side to the third vertex. In a parallelogram the base is any side. The height is the perpendicular distance between this side and the side parallel to it.
The perimeter of a parallelogram is the distance around the outside of the parallelogram. A parallelogram has four sides with opposite sides being congruent. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B).
