How does a trapezium look like?

A trapezoid is a four-sided flat shape with one pair of opposite parallel sides. It looks like a triangle that had its top sliced off parallel to the bottom. Usually, the trapezoid will be sitting with the longest side down, and you will have two sloping sides for the edges.

What is the property of trapezium?

Properties of quadrilaterals

Properties of quadrilaterals Rectangle Trapezium
Opposite Sides are parallel
All angles are equal
Opposite angles are equal
Sum of two adjacent angles is 180

How do you define a trapezoid?

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

Which angles of a trapezium are equal?

Mid-segment = (AB+ CD)/2

  • In isosceles trapezium, the legs or non-parallel sides are congruent.
  • The sum of the interior angles of the trapezium is equal to 360 degrees. i.e., ∠A + ∠B + ∠C + ∠D = 360°
  • The sum of the two adjacent angles is equal to 180°. This means that the two adjacent angles are supplementary.

What is trapezium formula?

A trapezium, also known as a trapezoid, is a quadrilateral in which a pair of sides are parallel, but the other pair of opposite sides are non-parallel. The area of a trapezium is computed with the following formula: Area = 1 2 × Sum of parallel sides × Distance between them .

What are the five properties of trapezium?


  • A pair of opposite sides are parallel.
  • Number of vertices 4.
  • Number of edges 4.
  • Area =1/2 × sum of parallel sides × height.
  • Perimeter = sum of length of side of trpezoid.

Why is the area of trapezium?

The area of trapezium depends on its parallel sides and distance between the parallel sides. If we know the length of parallel sides and the distance between them, then we can easily find the area of trapezium.

How do you prove a trapezium?


  1. has at least one pair of parallel sides.
  2. legs congruent.
  3. base angles congruent.
  4. diagonals congruent.
  5. opposite sides supplementary.

How is the area of trapezium derived?

Trapezoid Area Formula. According to the trapezoid area formula, the area of a trapezoid is equal to half the product of the height and the sum of the two bases. Area = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).

What is the area and perimeter of trapezium?

We know that that the perimeter of a figure is equal to the sum of the length of all of its sides. Perimeter of trapezium ABCD = 2.5dm + 5dm + 4dm +3dm. Perimeter of trapezium ABCD = 14.5dm —(1). From the figure, we can see that the area of trapezium ABCD = area of Rectangle AEDC + area of triangle DEB —(2).

What is the difference between a trapezium and a trapezoid?

Trapezoid — a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. Trapezium — a 4-sided flat shape with straight sides and NO parallel sides.

What is a trapezium used for?

Right trapezoids are used in the trapezoidal rule for estimating areas under a curve. An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base. An isosceles trapezoid is a trapezoid where the base angles have the same measure.

Are all rectangles trapezium?

NO. A trapezoid is defined (in North America) to be a quadrilateral that has exactly one pair of parallel sides. A quadrilateral with two pairs of parallel sides is called a parallelogram; a parallelogram with right angles is a rectangle.

Is a kite a trapezium?

A kite is a quadrilateral with two pairs of equal adjacent sides. A trapezium is a quadrilateral with one pair of parallel opposite sides. A parallelogram is a quadrilateral with two pairs of parallel opposite sides. A rhombus is a parallelogram with equal adjacent sides.

Is a square a trapezium?

A trapezium is a trapezoid, therefore it cannot be a square. A square has four congruent sides and angles. The most congruent sides a trapezium can have is three.

Does a trapezoid have right angles?

The trapezoid has two right angles.

Are angles of rhombus 90?

In Euclidean geometry, a rhombus is a special type of quadrilateral that appears as a parallelogram whose diagonals intersect each other at right angles, i.e., 90 degrees. Besides having four sides of equal length, a rhombus holds diagonals that bisect each other at 90 degrees, i.e., right angles.

Does a trapezoid have four right angles?

Trapezoids. A trapezoid is a quadrilateral, which means it has four sides. Two sides must be parallel to each other for it to be a trapezoid. A trapezoid also has four angles.

Can a trapezoid have 3 right angles?

A trapezoid cannot have three right angles. The total of the measures of the four interior angles of any quadrilateral always add up to 360 degrees. …

How many parallel lines does a trapezoid have?

A trapezoid is a quadrilateral with only one set of parallel sides. They absolutely cannot have two sets of parallel sides.

How many angles do a trapezoid have?

4 angles

What are 2 types of trapezoid?

  • A trapezoid is a quadrilateral with one pair of parallel sides.
  • There you have it, a trapezoid!
  • The altitude of a trapezoid is its height.
  • A scalene trapezoid has four sides of unequal length.
  • An isosceles trapezoid has legs of equal length.
  • A right trapezoid has one right angle (90°) between either base and a leg.

What are the 4 properties of a trapezoid?

The properties of the isosceles trapezoid are as follows:

  • The properties of trapezoid apply by definition (parallel bases).
  • The legs are congruent by definition.
  • The lower base angles are congruent.
  • The upper base angles are congruent.
  • Any lower base angle is supplementary to any upper base angle.

Does a trapezium have 4 different angles?

A trapezium has four angles.

Can a trapezium have two right angles?

Explanation: A trapezoid can have either 2 right angles, or no right angles at all.

What makes a trapezoid unique?

As a quadrilateral, the trapezoid is a four sided shape. The first unique property about the trapezoid is that it has only one pair of parallel sides. Trapezoids sometimes have different side lengths and different angle measures, but all the angles add up to 360 degrees as in any quadrilateral.

What are the rules of a trapezoid?

The bases (top and bottom) of an isosceles trapezoid are parallel. Opposite sides of an isosceles trapezoid are the same length (congruent). The angles on either side of the bases are the same size/measure (congruent). The diagonals (not show here) are congruent.

How many sides does a trapezoid have?
