Is a rectangle a parallelogram always sometimes or never?
Is a rectangle a parallelogram always sometimes or never?
DEFINITION of RECTANGLE: A parallelogram with all 4 interior angles congruent to each other is called a rectangle. So, straight from a definition we see that any rectangle is a parallelogram with additional property of having all interior angle congruent to each other.
Is a parallelogram a rectangle?
A rectangle is a quadrilateral in which all angles are right angles. A rectangle is a parallelogram, so its opposite sides are equal.
Is a parallelogram always sometimes or never a trapezoid?
A trapezoid will have exactly one pair of parallel sides. Quadrilaterals will have four congruent sides. A trapezoid is a parallelogram.

What is a square but not a parallelogram?
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. 4. A square is a rhombus.
What do you call a four-sided shape with unequal sides?
Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same. All internal angles still add up to 360°, as with all other regular quadrilaterals.
What do you call a quadrilateral with no parallel sides?
A trapezoid is a quadrilateral with exactly one pair of parallel sides. In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.) An isosceles trapezoid is a trapezoid whose non-parallel sides are congruent.
Does a rhombus have four square corners?
A rhombus is a four-sided shape where all sides have equal length (marked “s”). Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they “bisect” (cut in half) each other at right angles.
