THEOREM: If a quadrilateral is a parallelogram, it has 2 sets of opposite angles congruent. THEOREM: If a quadrilateral is a parallelogram, it has consecutive angles which are supplementary. THEOREM: If a quadrilateral is a parallelogram, it has diagonals which bisect each other.

Theorem 1: In a parallelogram, the opposite sides are of equal length. Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram. Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other.

RHOMBUS- a quadrilateral in which all four sides are congruent. KITE- a quadrilater in which each pair of consecutive sides are congruent, but opposite sides are not congruent. FORMULAS- The reason these two polygons were grouped together is because they actually have the same formula for their areas.

We can classify quadrilaterals into two different groups; regular and irregular. A regular quadrilateral is a quadrilateral with all sides having equal length. An irregular quadrilateral is the opposite of this, so it is a quadrilateral that is not regular. ... Opposite sides have equal length, but they are not all equal.

There are five types of quadrilaterals. One common property of all quadrilaterals is that the sum of all their angles equals 360°. Let us look into the properties of different quadrilaterals.

If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If — AB ≅ — CD and — BC ≅ — DA , then ABCD is a parallelogram.

If the sides have equal lengths, then it is called a square. We can check that we have a rectangle by checking the slopes of the sides: they are parallel or perpendicular. Parallelogram are quadrilaterals with opposite sides parallel, but adjacent sides not perpendicular.

Definition A convex quadrilateral ABCD is called a ˆ parallelogram if the opposite sides AB, CD and BC, AD are parallel. A is a parallelogram having two adjacent sides rhombus congruent. A is a rhombus having two adjacent sides square perpendicular.

A rectangle is a quadrilateral with all four angles right angles. It follows form this that the opposite sides are parallel and of the same length. A square is a quadrilateral with all four angles right angles and all four sides of the same length.

In mathematics, a 'quadrilateral' is any four-sided plane shape that is closed, whereas a 'quadrangle' is any shape with. four angles. However, if a shape has four angles it also has four sides so a quadrangle is the same as a quadrilateral.

A parallelogram is a quadrilateral with two pairs of opposite (facing) sides that are equal length and parallel. The opposite angles are equal. A rhombus is a parallelogram with sides that are all equal lengths.

A quadrilateral is a four-sided polygon. ... A convex quadrilateral have interior angles 180 degrees or less, a concave quadrilateral has an interior angle measure greater than 180 degrees. Most common quadrilaterals are convex, and they do not have any interior angle measure greater than 180 degrees.

A quadrilateral is a parallelogram if each pair of opposite sides are equal. Proof: In ∆PQR and ∆RSP, PQ = SR, QR = SP (given) and PR is the common side. Hence, PQRS is a parallelogram.
