Rectangle. A rectangle is a shape with parallel opposite sides, combined with all 90 degree angles. As a type of parallelogram, it has opposite parallel sides. In a rectangle, one set of parallel sides is longer than the other, making it look like an elongated square.

How do you identify a rectangle?
Rectangle Definition
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.
Is a square a rectangle?
A rectangle is a special case of both parallelogram and trapezoid. A square is a special case of a rectangle.
Are all Quadrilaterals rectangles?
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
Are all rhombuses rectangles?
A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles.
Are all rhombuses kites?
A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other and only one pair of opposite angles are equal. All sides of a rhombus are equal and opposite angles are equal. So, all kites are not rhombuses.
Are all rectangles kites?
Yes, always. Is a kite a rectangle? Sometimes (when it’s a square).
Is a rectangle a kite yes or no?
A rectangle has 4 right angles, and a square has four equal sides and four right angles.Likewise, every square is also a rectangle, because a rectangle has 4 right angles, but every rectangle is not a square. Kites. Kites are a special type of quadrilateral with two distinct pairs of consecutive sides the same length.
What is every rectangle?
A rectangle, by definition, is a polygon with four sides and four right angles. Every rectangle is a quadrilateral because all rectangles must have four sides, which is the definition of a quadrilateral.
Is a trapezoid a rectangle?
The definition of a trapezoid is that it is a quadrilateral with exactly one pair of parallel sides. Rectangles and squares have two pairs of parallel lines. Using the idea of exactly one pair of parallel sides, the trapezoid cannot be a square or rectangle.
Are parallel sides?
Two sides or lines are parallel if they are lines that are always the same distance from each other and will never intersect or touch. Parallel lines. The two lines above are parallel.That is what it means to be parallel.
Is a diamond a rhombus yes or no?
Diamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal.
Are all trapezoids isosceles?
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.
| Isosceles trapezoid | |
|---|---|
| Edges and vertices | 4 |
| Symmetry group | Dih2, [ ], (*), order 2 |
| Properties | convex, cyclic |
Can we draw a quadrilateral of ABCD with the following?
First we draw a rough sketch of quadrilateral ABCD and write down its dimensions, as shown. Step 1: Draw AB = 4.8 cm. Step 2: With A as center and radius equal to 6 cm, draw an arc. Step 3: With B as center and radius equal to 4.3 cm, draw another arc, cutting the previous arc at C.
Is every parallelogram a trapezium?
We know, a parallelogram is a special type of quadrilateral that has equal and parallel opposite sides.Therefore every parallelogram is not a trapezium.
Are all Quadrilaterals rectangles True or false?
Quadrilateral: A closed figure with four sides. For example, kites, parallelograms, rectangles, rhombuses, squares, and trapezoids are all quadrilaterals.Rectangle: A parallelogram with four 90 degree angles.
Are all rectangles square?
All squares are rectangles, but not all rectangles are squares. All squares are rhombuses, but not all rhombuses are squares.
Can trapezoids be kites?
A kite is a quadrilateral with two pairs of adjacent sides of identical length.A trapezoid (British: trapezium) can be a kite, but only if is also a rhombus. An isosceles trapezoid can be a kite, but only if it is also a square.
How do you describe a rectangle to a child?
In geometry, a rectangle is a shape with four sides and four corners. The corners are all right angles. It follows that the pairs of sides opposite each other must be parallel and of the same length.
What is rectangle example?
The definition of a rectangle is a four-sided figure or shape with four right angles that isn’t a square. An example of a rectangle is the shape of a an 8×10 picture frame. Any four-sided plane figure with four right angles. Any such figure or shape that is not a square; oblong.
How many sides are there in a rectangle?
4
