- If the shape is below another, then it is always the shape above it as well. So a rhombus is always a parallelogram, a square is always a rectangle, and always a parallelogram, and always a quadrilateral, etc. If I could draw the arrows in this reply it would look better.

- A square is a special kind of rhombus in which all angles are equal. A rhombus may or may not have all angles equal, so a rhombus does not have to be a square. On the other ha … nd, any figure with four equal sides is a rhombus and all squares have four equal sides so every square is a rhombus.   Other examples of the same situation. Some US coins are dimes. So every US dime is a coin, but not every coin is a US dime.

- In Euclidean geometry, a rhombus(◊), plural rhombi or rhombuses, is a simple (non-self-intersecting) quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.

Quadrilaterals A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The Parallelogram A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles a are the same, and angles b are the same).

Commencement of Laytime - Davies 1. A rhombus is a parallelogram with four congruent sides. While the definition states parallelogram, it is sufficient to say:  A quadrilateral is a rhombus if and only if it has four congruent sides., since any quadrilateral with four congruent sides is a parallelogram.

Quadrilaterals A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length. A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal.

Properties of Rectangles, Rhombuses, and Squares Definition: A rhombus is a quadrilateral with four congruent sides. Similar to the definition of a rectangle, we could have used the word parallelogram instead of quadrilateral in our definition of rhombus. Thus, rhombuses have all of the properties of parallelograms (stated above), along with a few others.

Quadrilaterals A rhombus is sometimes called a rhomb or a diamond. A square has equal sides and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). A parallelogram has opposite sides parallel and equal in length.

- They all agree that a rhombus is an equilateral parallelogram, but one says the angles are oblique, one says the angles are USUALLY oblique (implying that they don't have to be), and one specifically says the angles are NOT right angles. So, what's the official word?

Classification of Quadrilaterals An equiangular quadrilateral, i.e. the one with all angles equal is a rectangle. All angles of a rectangle equal 90°. An equilateral quadrilateral, i.e. the one with all sides equal, is a rhombus. In a square, rectangle, or rhombus, the opposite side lines are parallel. A quadrilateral with the opposite side lines parallel is known as a parallelogram. If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. A trapezoid, in which the non-parallel sides are equal in length, is called isosceles.

Properties of Rectangles, Rhombuses, and Squares Notice that the definition of a square is a combination of the definitions of a rectangle and a rhombus. Therefore, a square is both a rectangle and a rhombus, which means that the properties of parallelograms, rectangles, and rhombuses all apply to squares. Because squares have a combination of all of these different properties, it is a very specific type of quadrilateral.

What shape am I? A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides.

Quadrilaterals The Rhombus. A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines in second figure) meet in the middle at a right angle. In other words they bisect (cut in half) each other at right angles. A rhombus is sometimes called a rhomb or a diamond.

What are facts about a rhombus? A rhombus is a quadrilateral whose four sides all have the same length. 1) The rhombus is often called a diamond, after the diamonds suit in playing cards, or a lozenge, though the latter sometimes refers specifically to a rhombus with a 45â° angle.

All-1B-allanswer - CHAPTER 14 CHEMICAL KINETICS PRACTICE... No, because all four sides of a rectangle don't have to be equal. However, the sets of rectangles and rhombuses do intersect, and their intersection is the set of squaresall squares are both a rectangle and a rhombus. We can put squares in the intersection of the two circles.

Is every rhombus a parallelogram? A parallelogram has 2 pairs of parallel sides. End of story. It can be proved that opposite sides are equal length and diagonals bisect, but that’s another story. A rhombus is a special case of a parallelogram with all sides being equal. It can be proved the diagonals intersect at right angles. But it’s not part of the definition. Squares and rectangles are rhombi and parallelograms, respectively.

- 3. A parallelogram is a rectangle if and only if its diagonals are congruent. Construction workers use the fact that the diagonals of a rectangle are congruent (equal) when attempting to build a square footing for a building, a patio, a fenced area, a table top, etc. Workers measure the diagonals. Rhombus I have all of the properties of the parallelogram PLUS - 4 congruent sides-diagonals bisect angles-diagonals perpendicular. Using the definition, the properties of the rhombus. can be proven true and become theorems. When dealing with a rhombus, the definition and theorems are stated as ...
