It's so simple. a.Take 20cm, 36cm as the diagonal, and 22cm as the side to look at the triangle formed by the diagonal focus as the vertex.
10, 18, 22 for three sides.
The sum of the two sides is greater than the third side, and the difference between the two sides is less than the third side.
b.Take 6cm, 10cm as the diagonal, and 4cm as the side to look at the triangle with the diagonal focus as the vertice.
Three-sided for 3, 5, 4 OK.
The sum of the two sides is greater than the third side, and the difference between the two sides is less than the third side.
c.Take 60cm as a diagonal, 20cm, 34cm as two adjacent sides are not 20+34 60
d.Take 6cm as a diagonal, 3cm and 10cm as two adjacent sides.
No, 6+9 10

I think it's only ab
Because a parallelogram can consist of two congruent triangles, the triangle can be determined when the two diagonals and one side of the parallelogram (or two adjacent sides and one diagonal) are known, and only option A qualifies, judging by the axiom that the sum of any two sides of the triangle is greater than the third side.
If I have something wrong, please let me know, thank you

AB: I learned this when I was in elementary school.
-
ACB is not good, because 4+6=10, according to the sum of the two sides of the triangle is greater than the third side, these 3 line segments do not form a triangle, and therefore do not form a parallelogram.
Again, according to this axiom, my answer can be obtained.

The answer is "A".
Because a parallelogram can be divided into two congruent triangles if the diagonal is the common side, and the sum of the two adjacent sides of the parallelogram is less than the diagonal, then the triangle cannot be established, so it can only be "a".

1. The parallelogram is equal to each other, draw two parallel lines of equal length, and connect them. 2. Take one grid as a unit, draw three grids in the horizontal square and three grids in the vertical square. This is the square, which is a type of parallelogram.
3. Draw six squares horizontally and three vertically. This is the rectangle, which is also a parallelogram. 4. One is drawn on the left and the other is on the right, then you can draw two parallelograms of different shapes in the picture you give.
5. To make a parallelogram, it can be considered from the properties of the parallelogram, such as the opposite sides are equal to each other, the opposite sides are equal, a group of opposite sides are parallel and equal, the opposite angles are equal, the adjacent angles are complementary, the diagonals are bisected with each other, and so on. Find out the connection between the knowledge conditions of the book and the figure to be made, so as to find out the method of drawing.
Questions. Eight meters, eight meters and five meters, five meters draw five different parallelograms.
I'm talking about the different quadrilaterals of five, five, and eight, eight, eight.
What are the steps to draw a quadrilateral?
Do you answer the teacher?
There are no steps to this, just draw it. Questions.
What's the matter, pro.,It's just a matter of drawing a figure.,It's okay to draw any side first.,Oh dear.。

The 1st, 2nd, and 4th figures are parallelograms.
The height is not the only way to draw high) take any point from the two sides parallel to each other (generally select the vertices) to make a perpendicular line to its opposite side, and the height drawn should be represented by a dotted line.
A parallelogram is a closed figure composed of two sets of parallel line segments in the same two-dimensional plane. Parallelograms are generally named with the name of the figure plus four vertices. Note:
When using letters to represent a quadrilateral, be sure to indicate the vertices in a clockwise or counterclockwise direction.
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel edges. The opposite or opposite sides of the parallelogram have the same length, and the opposite angles of the parallelogram are equal.
In contrast, a quadrilateral with only a pair of parallel sides is trapezoidal. The three-dimensional counterpart of a parallelogram is a parallelepiped.
A group of quadrilaterals with two opposing sides parallel to each other is called a parallelogram.
1. Parallelograms belong to plane figures. Repentance.
2. Parallelograms belong to quadrilaterals.
3. The parallelogram belongs to the center symmetry figure.
The opposite sides of a parallelogram are parallel (by definition) and therefore never intersect.
The area of a parallelogram is twice the area of the triangle created by one of its diagonals.
The area of the parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.
Any line that passes through the midpoint of the parallelogram bisects the region.
Any non-degenerate affine transformation takes the parallelogram of a parallelogram.
The parallelogram has rotational symmetry of order 2 (to 180°) (or order 4 if it is square). If it also has two-row reflective symmetry, then it must be a diamond or rectangle (non-rectangular rectangle). If it has four lines of reflective symmetry, it is a square.
The circumference of a parallel pose quadrilateral is 2 (a + b), where a and b are the lengths of the adjacent sides.
Unlike any other convex polygon, a parallelogram cannot be engraved on any triangle that is less than two times its size.
At the center of the four squares constructed on the inside or outside of the parallelogram are the vertices of the squares.

What can be used to draw a parallelogram is as follows:<>1. By definition: make two sets of parallel lines.
2. According to the method of equal to the opposite side: first make DAB, and then use a compass, respectively with b and d as the center of the circle, and ad and ab as the radius to draw the intersection at c.
3. Diagonal bisection: make δabc, take the midpoint O of AC, connect BO and extend it to C.
The method of drawing a parallelogram is determined by the nature of the parallelogram:
1. The two pairs of opposite sides of the parallelogram are equal;
2. The two sets of diagonal diagonals of the parallelogram are equal;
3. The adjacent angles of the parallelogram complement each other.
