Quick Answer: What is a rectangle?

Is a rectangle a square?

A square is also a parallelogram whose sides intersect at 90° angles. Therefore, like a rectangle its opposite sides are congruent. A rectangle is a square when both pairs of opposite sides are the same length. This means that a square is a specialized case of the rectangle and is indeed a rectangle.

What is the simple definition of a rectangle?

Rectangle – Definition with Examples A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. The opposite sides of a rectangle have the same lengths and are parallel.

What is rectangle short answer?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square. A rectangle is characterized by length (L) and width (W).

What does a rectangle equal to?

Proof: This follows directly from the Quadrilateral Sum Conjecture which says that the sum of angles in any convex quadrilateral is equal to 360 degrees. Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.

Why can’t a rectangle be a square?

Definition: A square is a quadrilateral with all four angles right angles and all four sides of the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.

Is a rhombus a rectangle?

The dual polygon of a rhombus is a rectangle: 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.

Why is it called a rectangle?

The word rectangle comes from the Latin rectangulus, which is a combination of rectus (as an adjective, right, proper) and angulus (angle).

How do u find the square of a rectangle?

A special type of rectangle, called a square, has four equal sides. Because the sides are equal, when we multiply the length and width, we get a number times itself, or a number squared. use A = s2.

What is the rule for area of a rectangle?

To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.
