I don’t really know about the quadrilateral, but even if it were a parallelogram, it is impossible that it be a triangle.
In case you were wondering, the quadrilateral is an area of the plane that is the area of a square in which two diagonals intersect. To find the area of this parallelogram, it’s just as easy as figuring out how much floor space a square is.
Actually, even if it were a parallelogram, its actually a quadrilateral, so it cannot be a triangle. This is because of the fact that a parallelogram cannot be constructed in a single line unless all its sides are parallel.
A triangle is a two-sided figure in which all its sides are equal. A triangle is a figure in which the sum of the lengths of its three sides is equal to the length of its hypotenuse. A “hypotenuse” is a figure that has sides that are equal but not necessarily parallel. A quadrilateral is a figure that has equal sides and a hypotenuse. A rectangle is a figure in which all of its sides are equal.
The quadrilateral is a figure that can be constructed in a single line if the sides are equal and the sides are not parallel. The rectangle is a figure that cannot be constructed in a single line unless the sides are equal and the sides are not parallel. The triangle is a figure that can be constructed in a single line if the sides are equal but not necessarily parallel. The figure is a parallelogram if and only if all its sides are equal and the sides are not parallel.
The quadrilateral and the rectangle are both used in this figure as a building block, both with sides that are equal to the length of the triangle and both with sides that are not parallel to each other. That the quadrilateral is constructed in a single line is because it is built up from the square and triangle, so it is a figure that can be built in a single line if the sides are equal and the sides are not parallel.
The fact that the sides of the quadrilateral are the length of the triangle means that the sides of the quadrilateral that are parallel to one another must be equal to the length of the triangle. Which is an indication that the sides of the triangle must be equal to the sides of the quadrilateral.
The proof is in the pudding. You see, the quadrilateral is built from the square and triangle, so that means that the sides are equal. This means that the sides of the parallelogram that are parallel to one another must be equal to the length of the square. If the parallelogram is built from two parallelograms, the sides of the parallelogram that are parallel to one another must be equal to the length of the two parallelograms.
This is a very cool proof. It shows that if you can’t figure out the answer to the previous question, then you can’t figure out the answer to the next question either. This also helps you avoid making the same mistake twice. If you can’t figure out the answer to the previous question, then you should at least try to figure out the answer to the next possible question.
