Apr 30, 2018 · An isosceles trapezoid (called an isosceles trapezium by the British; Bronshtein and Semendyayev 1997, p. 174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal.
In an isosceles trapezoid, non-parallel sides are equal, base angles are equal, diagonals are congruent, and opposite angles are supplementary. Why is it called isosceles trapezoid? Isosceles means “equal legs.”
- Isosceles means “equal legs.” In an isosceles trapezoid, the non-parallel sides (or legs) are of equal length. Thus, it is called an isosceles trap...
- The number of sides in an isosceles trapezoid is four. While the two bases (opposite sides) are parallel to one another, the other two sides are eq...
- A right trapezoid is a trapezoid that has two adjacent right angles.
- A trapezoid in which all the four sides are of different lengths is called a scalene trapezoid.
Oct 9, 2024 · Isosceles trapezoids shapes have parallel top and bottom lines (bases). The other two lines are equal length, but aren’t parallel. This means the base angles and diagonals of an isosceles trapezoid are equal. Scalene trapezoid. A scalene trapezoid has sides that are different lengths and non-congruent.
An isosceles trapezium has: One pair of unequal parallel sides. Two non-parallel equal sides. Two pairs of adjacent equal angles. Diagonals that are equal in length. One line of symmetry.
In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of equal measure, [1] or as a trapezoid ...

Jul 9, 2021 · The properties of the isosceles trapezoid are as follows: The properties of a 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. The diagonals are congruent.
