## What is any side of a parallelogram called?

The parallel sides are called bases while the nonparallel sides are called legs. If the legs are congruent we have what is called an isosceles trapezoid.

## Do parallelograms have sides?

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

## What do the sides of a parallelogram equal?

Properties of Parallelogram Related to Sides and Angles

Opposites sides of a parallelogram are equal and parallel to each other. All the angles of a parallelogram add up to 360o. ∠A + ∠B + ∠C + ∠D = 360o.

## Do all parallelograms have 4 equal sides?

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.

## Are all sides congruent in a parallelogram?

All of the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). All sides are congruent by definition. The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

## Do all sides of a parallelogram have the same length?

A parallelogram has six sides. Opposite sides of a parallelogram are parallel. A parallelogram can have one pair or two pairs of parallel sides. All sides of a parallelogram have the same length.

## What is a parallelogram with four congruent sides?

A rhombus is a parallelogram with four congruent sides.

## How do you find the sides of a parallelogram when given the diagonals?

Explanation: In a parallelogram, the diagonals bisect one another, so you can set the labeled segments equal to each other and then solve for . \displaystyle x + 14 = 5x – 10 \rightarrow 24 = 4x \rightarrow 6 = x. If , then you substitute 6 into each labeled segment, to get a total of 40.

## How do you find the fourth side of a parallelogram?

We know that the opposite sides of a parallelogram are equal to each other. So, AB = CD and BC = AD. x=9 and y=4. Hence, the fourth vertex is (9,4).

## How do you find the angles of a parallelogram with sides?

This can also be calculated by the formula, S = (n − 2) × 180°, where ‘n’ represents the number of sides in the polygon. Here, ‘n’ = 4. Therefore, the sum of the interior angles of a parallelogram = S = (4 − 2) × 180° = (4 − 2) × 180° = 2 × 180° = 360°.

## Is opposite sides of parallelogram are equal?

The opposite sides of a parallelogram are equal. The diagonals of a parallelogram bisect each other.

## How are the lengths of the four sides of the parallelogram related?

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.

## How do you find the missing vertices of a parallelogram?

Step 1: Find the slope of the two sides connecting the pairs of given vertices of the parallelogram. Step 2: Since the opposite sides of the parallelogram are parallel to each other, their slopes are the same. Equate the slopes of the opposite lines, keeping (x,y) as the coordinates of the missing vertex.

## How do you find the vertices of a parallelogram?

4
Parallelogram/Number of vertices
Let the points (4, 5) (7, 6) (4, 3) (1, 2) represent the points A, B, C and D. Opposite sides of the quadrilateral formed by the given four points are equal. Also the diagonals are unequal. Therefore, the given points form a parallelogram.

## Does a parallelogram have four vertices?

In coordinate geometry, a parallelogram is similar to an ordinary parallelogram (See parallelogram definition ) with the addition that its position on the coordinate plane is known. Each of the four vertices (corners) have known coordinates.
