Square, Trapezoid, Kite Practice Page 2 20) Which choice must be true about parallelograms? A rhombus have four sides and all sides are equal with opposite sides are parallel. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). ⇐ FALSE: A rhombus MAY have 4 RA. A square MUST be a rhombus. I. Diagonals are perpendicular bisectors of each other. Fact #2: the square is a kind of rectangle: it’s a rectangle with all equal sides. • A rhombus MAY be a square. Rhombi or Rhombuses is a plural form of a rhombus. (2) Every rhombus is a square (3 Every trapezoid is a parallelogram 4 Every square is a rhombus 11. so B is false It is a parallelogram B. D. A base and its corresponding height must be perpendicular to each other. A) # $̅= 4 5̅ ( I know this notation is wrong, but some Parallelogram definition, a quadrilateral having both pairs of opposite sides parallel to each other. In physics, parallelograms are used to model individual force components and to describe vector addition. if abcd is also a rhombus, what must be the value of x? find the area and perimeter of the rhombus. A rhombus is a quadrilateral with all equal sides. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms! In Rhombus, opposite angles and sides are equal in length and parallel. The diagonals bisect each other. 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 a) Quadrilateral ABCD is a square.

Therefore: Statement: "A rhombus is a square." III. Example #1 : Determine if each figure is a rhombus, rectangle, or square. With a rhombus, all four sides are the same length.It therefore has all the properties of a parallelogram. Two pairs of sides are parallel. Its a bit like a square that can 'lean over' and the interior angles need not be 90°. Theorem 53: The diagonals of a rhombus … 1)I and II 2)I and III 3)II and III 4)I, II, and III If adjacent angles are congruent, which statement must be true? Q. Move the picture to a public website, or describe it. Compare and Contrast. Square – A parallelogram with four sides of equal length and angles of equal size (right angles). And since all sides are equal, so it must be a square and it could not be a rectangle. Because a square is a rectangle but a rectangle need not be a square, the most general quadrilateral that fits this description is a rectangle. Describe your findings. C. The diagonals are perpendicular bisectors. Since its opposite sides are equal, a rhombus is a parallelogram − this was our second test for a parallelogram in the previous module. d) Describe how you could use geometry software to test your conjecture in part c). Suppose you have a parallelogram with vertices A,B,C and D and is oriented as such: AB is parallel to CD (hence AD is parallel to BC). Quadrilateral ABCD is a parallelogram. To satisfy that this parallelogram is a rhombus, all sides must be equal. Rhombus is also known as diamond or rhombus diamond is a parallelogram and a four- sided quadrilateral. Any side of a parallelogram can be a base. Answer: 3 question Determine which quadrilaterals match the figure parallelogram, rhombus, rectangle, or square? When playing “Name That Quadrilateral,” your answer must be as general as possible.
