Isosceles trapezoid is a trapezoid in which the top and bottom sides are parallel, while the remaining two non-parallel sides have the same length. We know that a trapezoid is a quadrilateral with two parallel sides and two non-parallel sides. In an isosceles trapezoid, the non-parallel sides are equal. Thus, we can say that the parallel sides of a...
The properties of the isosceles trapezoid are discussed below. 1. Only one pair of sides is parallel. AB||CD 2. Non-parallel sides (legs) are equal in measure. AD=BC⇒c=d 3. The diagonals are equal. AC=BD 4. The base angles are congruent. ∠D=∠C;∠A=∠B 5. The opposite angles are supplementary. ∠D+∠B=180∘;∠C+∠A=180∘ 6. Line segments joining the midpoin...
Calculating the perimeter of a shape simply means finding the length around the shape. Let’s understand the steps using an example. Step 1: Recall the formula. The perimeter of an isosceles trapezoid is given by P=a+b+2c The lengths of the sides must simply be added because the perimeter is equal to the sum of the length of the shape’s borders. The...
The formula for the area of an isosceles trapezoid is given by A=12h(a+b), where a and b are the base lengths, and h is the height. Simply substitute the values in the formula. The area is measured in square units. So, apply the appropriate unit to the answer.
An isosceles trapezoid’s interior angles add up to 360 degrees.The non-parallel sides of an isosceles trapezoid are congruent.The median runs parallel to both bases, and its length is equal to the sum of the bases’ lengths.“Trapezium” is another name for a trapezoid.In this article, we learned about isosceles trapezoid, its properties, and formulas associated with it. Let’s solve a few examples to apply what we have learned!
Assuming that the isosceles trapezoid has an area of 128inches2and bases that are 12 inches and 20 inches long, determine its height.
1. The first type is an isosceles trapezium, which has two pairs of parallel sides. 2. The second type is a right trapezium, which has one pair of parallel sides and one pair of right angles. 3. The third type is an acute trapezium, which has one pair of parallel sides and two pairs of acute angles. 4.
If the legs or the non-parallel sides of the trapezium are of equal length, then it is called an isosceles trapezium. Scalene Trapezium A trapezium with all the sides and angles of different measures is called a scalene trapezium.
