There are exactly three possible ways to make a quadrilateral by combining two pentominoes.
Pentominoes are made of squares connected along their edges, so they have only right angles. This means the only quadrilaterals we can make from them will be rectangles. By definition, each pentomino has an area of 5 , so combining two of them will give us a rectangle made of 10 squares. This must be the 10x1 rectangle or the 5x2, because these are the only factors of 10.
All possibilities are listed below:
10x1 rectangle:
- Two 5x1 pentominoes connected end-to-end.
- Two "L pentominoes" laying on each other.
- Two "P pentominoes" poking into each other.

How do you calculate the sum of a quadrilateral?
You don't. There is no such thing as the "sum of a quadrilateral". If you mean the perimeter, you add the lengths of the four sides. If you want the area, you can divide the quadrilateral into two triangles, or some other shapes, calculate the individual pieces, and add everything up.
How do you make four triangles out of a quadrilateral by a line through it?
You cannot make four triangles our of a quadrilateral by ONE line through it. One line can give you at most two triangles. Two lines, each running from one vertex of the quadrilateral to the opposite vertex, will give 4 triangles.
What do two triangles make?
They can form into a 4 sided quadrilateral if they are the same size.
Can two sides of a quadrilateral be parallel?
Two sides of a quadrilateral can be parallel.
Maximum no of diagonals does quadrilateral have?
A quadrilateral has two and only two diagonals. That's the maximum and also the minimum. If it has more or fewer than two diagonals, it's not a quadrilateral.
What quadrilateral does two triangles make as a shape?
All of them.
Can a pentomino be 5 equal spuares in a line?
Sure. A pentomino is any figure you can make by laying squares side by side on a plane, with two adjacent squares touching with their entire length. This includes five in a line. In total (eliminating duplicates due to rotations and reflections), 12 different figures can be made this way.

What is the definition of pentomino?
The pentomino is a collection of five squares connected to each other completely on one or more sides, similar to the two squares of a traditional "domino", or to the "tetromino" forms found in the game Tetris. There are 18 regular pentomino shapes, including 6 that are mirror forms. There are also the rotated versions of the forms. (see the related link)

How many diagoanals does a Quadrilateral have?
A Quadrilateral has two diagonals. IF the quadrilateral is a rectangle, then the two diagonals are equal in length.

They can form into a 4 sided quadrilateral if they are the same size.
Can two sides of a quadrilateral be parallel?
Two sides of a quadrilateral can be parallel.

A quadrilateral with two pairs of adjacent sides?
Is a quadrilateral polygon.
How you can make an apron?
Take two pieces of cloth and sow them together. then take two thinner pieces and sow them to the sides.:)
A quadrilateral with only two and only two parallel sidea is a?
A quadrilateral with only two parallel sides is only a quadrilateral ...... because we don't know whether the parallel sides ar equal or not .............. so it is only a quadrilateral ............
