# What is the altitude of a rhombus?

altitude, the altitude of a rhombus is perpendicular distance from base to opposite side (which may have be extended).

Furthermore, what is the definition of the height of a parallelogram?

The length of the height is also known as the altitude of a parallelogram which is defined as the perpendicular distance between any pair of parallel lines. It is said to be the shortest distance between two opposite sides of a parallelogram.

What makes parallelogram special in relation to other Quadrilaterals?

A simple (non-self-intersecting) quadrilateral is a parallelogram if and only if any one of the following statements is true: Two pairs of opposite sides are equal in length. Two pairs of opposite angles are equal in measure. The diagonals bisect each other.

What are consecutive angles in a parallelogram?

Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right.

## Are Rhombuses always parallelograms?

As, if you change only a pair of adjacent sides of a parallelogram . A rhombus is always a parallelogram, but the opposite is not so. Just as a square is always a rectangle, but a rectangle is not always a square. Four equal sides make a rectangle a square and four .equal sides make a parallelogram a rhombus.

## Can you make a trapezoid with three right angles?

If, however, the definition states that two sides of a quadrilateral must be parallel and two other must not (notice, this is not a typical definition), then rectangle is not a particular type of trapezoid and Kevin could not draw a trapezoid with three right angles.

## Are squares a rhombus?

Some sources say yes, some say no. Some sources define a rhombus as a quadrilateral and parallelogram with equal sides, but without right angles. Some sources say a square is a special case of a rhombus. inclusive definition: A rhombus has four equal sides; i.e. the class of rhombi INCLUDES all squares.

## Are a square and a rhombus the same?

A square is a Rhombus because it has four sides, and each side is the same length, however a square has a further definition as a shape that has four equal angles of 90 degrees. Therefore, a square is a Rhombus, however a Rhombus is not necessarily a square.

## Is a square always a rhombus?

A parallelogram is a quadrilateral with two pairs of opposite sides parallel. A square is a rhombus with all the angles equal (to 90°). A rhombus does NOT have all the properties of a square, therefore is not a special kind of square.

## Is a polygon a rhombus and why?

A regular polygon must be equilateral (all sides the same length) and equiangular (all internal angle sof the same size). A rhombus has 4 sides of equal length and opposite angles are equal but not all angles are equal. A rhombus may be shaped like a diamond. A rhombus that is equiangular is called a square.

## What is the formula for the area of a regular polygon?

Each of the triangles are equal in base length, height, and area. Remember the formula for the area of a triangle. The area of any triangle is 1/2 times the length of the base (which, in the polygon, is the length of a side) multiplied by the height (which is the same as the apothem in regular polygon).

## What is the difference between a rhombus and a parallelogram?

Difference Between Rhombus and Parallelogram. A parallelogram is a quadrilateral or four-sided figure in which the opposite sides are parallel. And because the opposite lines are parallel, hence the opposite angles are also equal. A rhombus, on the other hand, may be defined as an equilateral parallelogram.

## Are all squares Rhombuses and why?

Square – a parallelogram with four equal sides and four right angles. A square meets the definition of a rhombus. So, yes, all squares are rhombuses but not all rhombuses are squares.

## Is a square is a rhombus?

A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. A square however is a rhombus since all four of its sides are of the same length.

## Are all rectangles a rhombus?

Rhombuses may be rectangles, as long as the shape is a square. Every square is a rectangle, and a rectangle can be a square if all four sides are the same length. Every square is a rhombus, and a rhombus can be a square, if all its angles are 90 degrees.

## Is a rhombus and a diamond the same thing?

Both are quadrilaterals. Usually a diamond (at least at the elementary school level) is drawn as a rhombus (all 4 sides congruent) or a kite (2 opposite pairs of congruent sides.) So every rhombus you draw, a layman would call it a diamond, but you can draw a “diamond” that a mathematician wouldn’t call a rhombus.

## How do you find the area of a polygon?

Write down the formula for finding the area of a regular polygon. To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.

## How many right angles are in a rhombus?

A square has got 4 sides of equal length and 4 right angles (right angle = 90 degrees). A Rhombus has got 4 sides of equal length and opposite sides are parallel and angles are equal. A parallelogram is a rectangle that has been pushed over.

four sides

## What makes a parallelogram a rhombus?

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). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!

## How do you find the area of a quadrilateral?

Method 1 Squares, Rectangles and Other Parallelograms

• Know how to identify a parallelogram.
• Multiply base times height to get the area of a rectangle.
• Multiply one side by itself to find the area of a square.
• Multiply the diagonals and divide by two to find the area of a rhombus.
• ## How do you find the area of a trapezium?

To calculate the area of a trapezium, divide it into a rectangle and two triangles as shown below. Now, piece together the triangular ends so that the trapezium is divided into a triangle and rectangle. The base of the triangle is the difference between the lengths of two parallel sides. That is, a – b.

## How do you make a rhombus?

An error occurred.

• Step 1: Draw a straight line AB 6 cm long.
• Step 2: Using a protractor draw an angle of 57° from Point A. Mark the Point D so that AD = 6 cm.
• Step 3: Using a ruler and a set square draw a line BC so that it is parallel to AD. Mark the Point C so that BC = 6 cm.
• Step 4: Join Point D to Point C.
