All rectangles are _____.

A quadrilateral is a _____ if it is both a rhombus and a rectangle.

A rectangle is a parallelogram with four congruent sides.

A parallelogram is a quadrilateral with exactly one pair of parallel sides.

A trapezoid is a rhombus with four right angles.

Each angle in a rectangle measures _____.

Every rectangle is _____ a rhombus.

All the four angles of a _____ are right angles.

A square is a quadrilateral with four congruent angles and four congruent sides.

A trapezoid is a quadrilateral with two pairs of parallel sides.

The sum of measures of interior angles of a quadrilateral is _____.

Every rhombus is _____ a trapezoid.

Are polygons with four sides and the sum of the measures of the angles is 360 degrees.

Is a parallelogram that has the properties of a rhombus and a rectangle. Its sides intersect at 90 degrees and all four sides are congruent.

Is a parallelogram with four right angles. A rectangle is a parallelogram, its opposite sides must be congruent and it must satisfy all other properties of parallelogram.

Is a four-sided plane rectilinear figure with opposite sides parallel.

Is a quadrilateral with one pair of parallel sides.

Is a type of parallelogram, and what distinguishes it shapes is that all four of its side are congruent.

Is a four-sided flat shape with straight sides that:

• - Has two pairs of sides

• - Each pair is adjacent sides (they meet) that are equal in length

• - Also the angles are equal where the pairs meet. Diagonals (dashed lines) meet at a right angle, and one of the diagonal bisects (cuts equally in half) the other.

Is a trapezoid where the legs have equal length. It can also be defined as a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides, making it automatically trapezoid.

A trapezoid is a quadrilateral.

A trapezoid is a quadrilateral with two pairs of parallel sides.

The legs are the parallel sides of the trapezoid.

A kite is a trapezoid.

A trapezoid is always a quadrilateral.

A quadrilateral is always a trapezoid.

The parallel sides of an isosceles trapezoid are congruent.

The length of the median of a trapezoid is one half the sum of the length of the bases.

The diagonals of a trapezoid are always congruent.

A rectangle is an equiangular quadrilateral.

Every quadrilateral is a parallelogram.

Some rectangles are rhombuses.

All squares are rectangles.
