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.”
An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure. In other words, if two opposite sides (bases) of the trapezoid are parallel, and the two non-parallel sides are of equal lengths, then it is an isosceles trapezoid.
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.
Aug 3, 2023 · An isosceles trapezoid is a two-dimensional closed figure with one pair of congruent non-parallel sides (legs) and two pairs of congruent base angles. In other words, an isosceles trapezoid is a trapezoid with congruent legs. Therefore, an isosceles trapezoid has a pair of parallel but unequal opposite sides (bases) and a pair of non-parallel ...
The Square. A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
Show Answer. Problem 2. ∠ABC = 130 ∠ A B C = 130 , what other angle measures 130 degrees? Show Answer. Problem 3. What is the value of j in the isosceles trapezoid below? Show Answer. Base Angles. Diagonals of Isosceles Trapezoid. Problem 3. The diagonals of an isosceles trapezoid are congruent.
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 ...
