NOTE: Squares, Rectangles and … Properties of Square Parallelogram: A quadrilateral that has its opposite sides congruent and parallel to each other is a parallelogram. Here are the seven quadrilaterals: Kite: A quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can’t be used in both pairs), Parallelogram: A quadrilateral that has two pairs of parallel sides, Rhombus: A quadrilateral with four congruent sides; a rhombus is both a kite and a parallelogram, Rectangle: A quadrilateral with four right angles; a rectangle is a type of parallelogram, Square: A quadrilateral with four congruent sides and four right angles; a square is both a rhombus and a rectangle, Trapezoid: A quadrilateral with exactly one pair of parallel sides (the parallel sides are called bases), Isosceles trapezoid: A trapezoid in which the nonparallel sides (the legs) are congruent. Properties of Rhombuses, Rectangles, and Squares, Interior and Exterior Angles of a Polygon, Identifying the 45 – 45 – 90 Degree Triangle. They are the only quadrilaterals in which all four angles They would never intersect because they are parallel. If you know what the quadrilaterals look like, their definitions should make sense and be pretty easy to understand (though the kite definition is a bit of a mouthful). squares.

The quadrilaterals with all angles congruent are rectangles and Imagine extending the pairs of opposite sides. A quadrilateral has two diagonals. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. Thus a rectangle or a rhombus, or any 4 sided shape that does not have all four sides the same length AND all angles 90 degrees. Menu. What quadrilateral has all angles congruent. Draw in its diagonals. A rectangle also has the special characteristic that all of its angles are right angles; all four of its angles are congruent. So if were to straighten it out a little bit, it's a rhombus so all the four sides are the same. Parallelogram Notice, also, that the opposite angles of a parallelogram are congruent, as are the opposite sides. 99. What was decided after the war about the re-building of the chathedral? So the answer is … There are seven quadrilaterals, some that are surely familiar to you, and some that may not be so familiar. Thus, you can say that a rectangle is a parallelogram but not that a parallelogram is a rectangle (a parallelogram is only sometimes a rectangle). A quadrilateral with both sides of opposite sides parallel. A quadrilateral has 2 pairs of congruent sides. But in either case, you have to have all four sides be congruent … A rectangle with four sides of equal length is a square. What type of quadrilateral is it? … Its opposite angles are also congruent to each other. Basic types of Quadrilateral Parallelogram : A quadrilateral having two pairs of parallel sides.
