# Are all 4 sided polygons with 2 pairs of equal sides parallelograms?

## Are all 4 sided polygons with 2 pairs of equal sides parallelograms?

A rectangle has two pairs of opposite sides parallel, and four right angles. 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.

### What polygon is a parallelogram that has all equal sides?

rhombus

#### Are all 4 sided shapes parallelograms?

All rectangles are parallelograms, but not all parallelograms are rectangles. And all of these shapes are quadrilaterals. The diagram below illustrates the relationship between the different types of quadrilaterals. You can use the properties of parallelograms to solve problems.

Does a parallelogram have two pairs of equal sides?

Parallelogram. A parallelogram has two pairs of equal sides. It has two pairs of equal angles. The opposite sides are parallel.

What are the 4 types of parallelograms?

There are three special types of a parallelogram.

• Rhombus: A parallelogram in which all sides are equal.
• Rectangle: A parallelogram in which all angles are right angles and the diagonals are equal.
• Square: A parallelogram with all equal sides and all angles equal to 90 degrees. The diagonals of a square are also equal.

## Is a kite always a quadrilateral?

In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

### Can you draw a quadrilateral with no parallel lines and no right angles?

The answer is true. All you need is one 90 degree angle, two 50 degree angles, and one 170 degree angle. This creates a weird looking shape that is a quadrilateral with no parallel lines and at least one right angle.

#### Can you draw a quadrilateral with no parallel lines?

Explanation: The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.

What quadrilateral has only 2 right angles?

trapezoid

Can a parallelogram have exactly 2 right angles?

A parallelogram is a quadrilateral with 2 pair of opposite sides parallel. A rectangle is a special parallelogram that has 4 right angles. However, a trapezoid could have one of the sides connecting the two parallel sides perpendicular to the parallel sides which would yield two right angles.

## Which Quadrilaterals can never have right angles?

A rhombus is a quadrilateral where all four sides are equal in length. Different from a square, a rhombus does not have to have four right angles.

### Does a trapezoid have equal angles?

The base angles of an isosceles trapezoid are equal in measure (there are in fact two pairs of equal base angles, where one base angle is the supplementary angle of a base angle at the other base).

#### How many equal angles does a trapezoid have?

four angles

What shape has exactly 3 right angles?

What shape has 3 right angles? Place a right triangle on top of a rectangle: At the base there are two right angles and at the top there is a third, so the figure has three right angles. As there is no specification for polygon , it can be square or rectangle also.

How many right angles does an L shape have?

four right angles

## Does a diamond shape have right angles?

A rhombus has four equal sides. The opposite sides are parallel, but the corners do not form right angles. A diamond shape is a good example of a rhombus. The opposite sides are equal, but the corners do not form right angles.

### Does a octagon have right angles?

An octagon is an eight-sided polygon. If an octagon is a regular octagon, then it has no right angles, or angles of measure 90°.

#### Does a triangle have right angles?

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

Which is the shortest side of right angle triangle?

In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.

What type of triangle can have one right angle?

A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.

## Do right triangles have equal sides?

A right triangle has one angle equal to 90 degrees. A right triangle can also be an isosceles triangle–which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles.

### Are the three sides of a right triangle always equal?

A triangle is what you get when you have an isosceles right triangle. If a triangle is a right triangle and it’s isosceles, then the two sides other than the right angle must add up to 90 degrees and they must be equal, so each must equal 45 degrees.

#### Can a right angled triangle have 3 equal sides?

Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

Does 5/12/13 make a right triangle?

Yes, a right triangle can have side lengths 5, 12, and 13. To determine if sides of length 5, 12, and 13 units can make up the sides of a right…
