are diagonals in a square equal?

All four angles of a square are equal. (Each is 360°/4 = 90°, so every angle of a square is a right angle.) All four sides of a square are equal. The diagonals of a square are equal.

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 symmetric diagonal matrix can be defined as a matrix that is both upper- and lower-triangular. The identity matrix In and any square zero matrix are diagonal. A one-dimensional matrix is always diagonal.

If the diagonals of a parallelogram are equal, then show that it is a rectangular. so ∠ BAD and ∠ CDA are right angles as they are congruent and supplementary.

Yes if diagonals of a parallelogram are equal then it is a rectangle. Let PQRS be a parallelogram. To show that PQRS is a rectangle, we have to prove that one of its interior angles is 90º.

In a parallelogram, the diagonals are equal. In a parallelogram, the diagonals bisect each other. In a parallelogram, the diagonals intersect each other at right angles. In any quadrilateral, if a pair of opposite sides is equal, it is a parallelogram.

A rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. ... The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.

All squares are similar. All rectangles are similar. ... Now, all squares are always similar. Their size may not be equal but their ratios of corresponding parts will always be equal.

Opposite sides are equal in length. The two diagonals are equal in length. It has two lines of reflectional symmetry and rotational symmetry of order 2 (through 180°).

Opposite sides of a square are both parallel and equal in length. All four angles of a square are equal.

If two squares have equal areas, they will also have sides of the same length. But although "equal areas mean equal sides" is true for squares, it is not true for most geometric figures. Consider the rectangles shown below. ... Two geometric figures are called congruent if they have the same size and the same shape.

If the diagonals of a parallelogram are perpendicular, it must be a rhombus. Diagonals of a parallelogram bisect the angles. A quadrilateral that has diagonals that bisect and are perpendicular must be a square.

The diagonals of a parallelogram bisect each other (and conversely: if the diagonals of a quadrilateral bisect each other, it is a parallelogram). If one pair of opposite sides of a quadrilateral is equal and parallel, then the quadrilateral is a parallelogram.

No, diagonals of a parallelogram are not perpendicular to each other, because they only bisect each other.
