what are the side lengths of a parallelogram?
314224
A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles.

If adjacent sides of a parallelogram are equal, then the parallelogram is a rhombus. In a rhombus, the diagonals bisect each other and are perpendicular to each other.

In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length.

The diagonals of a parallelogram are not of equal length. They bisect with each other at the point of intersection with equal sides across the point of intersection. This can be proved using the ASA criterion as well. When we divide the parallelogram through two diagonals, we see that four triangles are formed.

No, as a general rule the diagonals of a parallelogram do not bisect each other at right angles. The definition of a parallelogram is a four-sided polygon with opposite sides parallel and equal in length. ... For all parallelograms that are not squares, the diagonals do not intersect at right angles.

A parallelogram is a quadrilateral with opposite sides parallel. ... A rectangle is a parallelogram but with all four interior angles fixed at 90° A rhombus is a parallelogram but with all four sides equal in length. A square is a parallelogram but with all sides equal in length and all interior angles 90°

A parallelogram is a quadrilateral with opposite sides that are parallel and congruent. Congruent means exactly the same. In this case, a parallelogram has opposite sides that are parallel and congruent meaning that they have the same length. Here is a parallelogram.

Two adjacent sides of a parallelogram are in the ratio 5 : 7. If the perimeter of parallelogram is 72 cm.

The measures of the adjacent angles of a parallelogram add up to be 180 degrees, or they are supplementary. Then, AD ∥ BC and AB is a transversal. ... Thus, the sum of any two adjacent angles of a parallelogram is 180°. Hence, any two adjacent angles of a parallelogram are supplementary.

A parallelogram has no reflectional symmetry. A parallelogram has rotational symmetry of 180º (Order 2). Definition: A rectangle is a parallelogram with 4 right angles.

A parallelogram is a quadrilateral whose opposite sides are parallel. The opposite angles of a parallelogram are equal. The opposite sides of a parallelogram are equal. The diagonals of a parallelogram bisect each other.

Other properties. Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. The area of a parallelogram is twice the area of a triangle created by one of its diagonals. The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.

Answer. In a parallelogram if two diagonals are equal, then the parallelogram is a rectangle.So, ABCD is a rectangle.It is known that each interior angle of a rectangle is 90 degree. Since ABC is an interior angle of rectangle ABCD, so measure of angle ABC is 90 degree.
