Key learning points. All triangles have 3 straight sides and 3 vertices. Equilateral triangles have 3 equal sides and 3 equal angles. Isosceles triangles have 2 equal sides and 2 equal angles. Scalene triangles have no equal sides and no equal angles.
Jun 23, 2024 · A triangle with two sides of equal length is called an isosceles triangle. A triangle that has three sides of equal length is called an equilateral triangle . Figure 3.3.11 shows both types of triangles.
A trapezium is a quadrilateral in which only one pair of opposite sides are parallel to each other. An isosceles trapezium is a trapezium in which the non-parallel sides are equal in measure. In other words, the bases are parallel and the legs are equal in measure.

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.
An isosceles triangle with one angle greater than 90° is an obtuse-angled triangle. An isosceles triangle with angles of 100°, 40° and 40° is an obtuse-angled triangle.
