Why parallelogram has no lines of symmetry?
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
How do you figure out the area of a diamond?
Do exactly the same thing for a rhombus or a parallelogram A = base x height (parallelogram) OR A = 1/2 x diagonal 1 x diagonal 2
If one diagonal of a quadrilateral bisects the other when is the quadrilateral a parallelogram?
In this case, the quadrilateral is sometimes a parallelogram.
What quadrilateral has only one diagonal that is bisected?
Any quadrilateral that is not a parallelogram can have only one diagonal that is bisected by the other.
Prove that if the diagonal of a parallelogram does not bisect the angles through the vertices to which the diagonal is drawn the parallelogram is not a rhombus?
Suppose that the parallelogram is a rhombus (a parallelogram with equal sides). If we draw the diagonals, isosceles triangles are formed (where the median is also an angle bisector and perpendicular to the base). Since the diagonals of a parallelogram bisect each other, and the diagonals don't bisect the vertex angles where they are drawn, then the parallelogram is not a rhombus.
How do you calculate the sides of a parallelogram given the height and longer diagonal?
The height and longer diagonal do not provide enough information to calculate the sides.
How do you calculate a force by using the parallelogram method?
To calculate the resultant force using the parallelogram method, determine the individual forces acting on an object and represent them as vectors. Then, create a parallelogram with these vectors as sides, and the resultant force is represented by the diagonal of the parallelogram from the point of origin. Calculate the magnitude and direction of the resultant force using trigonometry.
In a parallelogram a diagonal separates the parallelogram into?
two congruent triangles
When a parallelogram is constructed in order to add forces what represents the resultant of the forces?
In a parallelogram of forces, the resultant force is represented by the diagonal of the parallelogram drawn from the initial point of the forces to the opposite corner. The magnitude and direction of the resultant force are determined by the length and orientation of this diagonal in the parallelogram.
What divides a parallelogram into two congruent triangles?
The term for the line that divides them is a diagonal.
Do parallelograms have diagonal sides?
A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.
How is the diagonal in parallelogram formed?
a squished rectangle
What is the diagonal of a parallelogram?
A parallelogram has two diagonals the same as all 4 sided quadrilaterals
Why drawing a diagonal on any parallelogram will always result in two congruent triangles?
Drawing a diagonal in a parallelogram divides it into two triangles that share the same base (the diagonal) and have equal heights, as the opposite sides of a parallelogram are equal in length and parallel. Additionally, each triangle has two sides that are equal to the lengths of the corresponding sides of the parallelogram. By the Side-Side-Side (SSS) congruence criterion, the two triangles formed by the diagonal are congruent. Thus, any diagonal in a parallelogram always results in two congruent triangles.
Are all parallelogram have diagonal of equal length?
No. Most do not.
Why parallelogram has no lines of symmetry?
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
E is the midpoint of ab and db is a diagonal of parallelogram abcd what is the ratio of areas of triangle Δabd to parallelogram abcd?
Either diagonal of a parallelogram divides the parallelogram into two triangles of equal areas. Thus area of triangle abd = half that of the parallelogram abcd. The required ratio is 1 / 2.
