We can do this by showing that that the diagonals are congruent or by showing that one of the angles is a right angle. Squares have four congruent sides and four angles that measure 45 degrees. A rectangle is cyclic: all corners lie on a single circle. Solution: Given: a = 10 cm. A rectangle is closed flat shape, having four sides, and each angle equal to 90 degrees. Therefore, the perimeter of a rectangle is 30 cm. Is the statement true always, sometimes, or never? The opposite angles are congruent, the diagonals bisect each other, the opposite sides are parallel, the diagonals bisect the angles Which statement describes the properties of a rhombus select all that apply has rotational symmetry of order 2 about its centre or 4 if it is also a square (i.e. Charts: Sides, Diagonals, Angles. Select all that apply. The properties that all rectangle shares include: All rectangles have 2 pairs of sides that are equal and opposite to each other In all rectangles, the exterior and interior angles are 90 degrees. A rectangle is a four-sided shape where every angle is a right angle (90°). A rectangle is characterized by length (L) and width (W).

All sides and angles are congruent. 2. anwser. Suppose, length of rectangle is 5cm and width is 4 cm, then the area will be: is a four sided-polygon, having all the internal angles equal to 90 degrees. A rectangle is not always a square. Hence, the length of the diagonal of rectangle will be: Solution- We know that the area of a rectangle is given by $$A = Length \times Width$$. answer choices . All of them are quadrilaterals. 1. The diagonals are perpendicular. Definitions and formulas for the perimeter of a rectangle, the area of a rectangle,  how to find the length of the diagonal of a rectangle, properties of the diagonals of a rectangle. 2 Answers.
