If the diagonals of a parallelogram are congruent , then it’s a rectangle (neither the reverse of the definition nor the converse of a property). If a parallelogram contains a right angle, then it’s a rectangle (neither the reverse of the definition nor the converse of a property).
How do you identify a rectangle?
For a shape to be a rectangle, it must be a four-sided polygon with two pairs of parallel, congruent sides and four interior angles of 90° each . If you have a shape that matches that description, it also is all this: A plane figure. A closed shape.
What makes a rectangle a rectangle?
A rectangle is a 2D shape in geometry, having 4 sides and 4 corners . Its two sides meet at right angles. Thus, a rectangle has 4 angles, each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel.
Is a rectangle a rectangle?
Rectangle: A rectangle is a two-dimensional figure with four sides , four interior right angles, and four corners. The opposites sides of a rectangle are equal. A rectangle has four angles, with each angle measuring 90o. Similar to a square, a rectangle is also referred to as an equiangular quadrilateral.
What is the rule for a rectangle?
To qualify as a rectangle, the shape must have four sides with four right angles whose opposite sides are parallel and equal in length to each other with diagonals of equal length and intersecting at their midpoints.
What angle is a rectangle?
A rectangle is a quadrilateral. The opposite sides of a rectangle are equal and parallel to each other. The interior angle of a rectangle at each vertex is 90° . The sum of all interior angles is 360°.
Can a rectangle have equal sides?
A rectangle has four sides, but these are not all equal in length . The sides parallel to each other are congruent.
Is every rhombus a rectangle?
No, every rectangle is not a rhombus .
Is a square always a rectangle?
A rectangle is a quadrilateral, all of whose angles are equal i.e. right angles. Square, apart from all equal angles, also has all sides equal. Hence, square is a special case of rectangle. ... A square is always the rectangle , but a rectangle is a square only when it has all sides equal...
What kind of shape is a rectangle?
A rectangle is a 2D shape with four straight sides and four right angles . Opposite sides of a rectangle are the same length and one pair of opposite sides are often longer than the other pair. If all of the sides of a rectangle are the same length, it is a special type of rectangle called a square.
How do I find the diagonal of a rectangle?
Explanation: You can find the diagonal of a rectangle if you have the width and the height . The diagonal equals the square root of the width squared plus the height squared.
How do you find the sides of a rectangle?
A rectangle is a closed two-dimensional figure with four sides and four corners . The length of the opposite sides is equal and parallel to each other.
What is the square area of a rectangle?
| The formula for the Area of a Rectangle | The perimeter of a Rectangle P= 2(l + b) | Area of a Rectangle A = l × b |

How does a rectangle look like?
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. Two sides are said to be parallel, when the distance between them remains the same at all points.
Are all sides congruent in a rectangle?
All of the properties of a rectangle apply (the only one that matters here is diagonals are congruent). All sides are congruent by definition . All angles are right angles by definition.
