Do all isosceles trapezoids have reflectional symmetry?

Yes. An isosceles trapezoid has congruent sides between the two parallel sides. If you were to draw two right triangles using the height of the trapezoid as one leg and the congruent sides as the hypotenuses then by HL you know the two triangles are congruent. read more

Yes. An isosceles trapezoid has congruent sides between the two parallel sides. If you were to draw two right triangles using the height of the trapezoid as one leg and the congruent sides as the hypotenuses then by HL you know the two triangles are congruent. Removing these two triangles leaves a rectangle behind. read more

An isosceles trapezoid is a four sided figure with only two opposite sides parallel. The base angles are equal and and the angles to the other parallel line are also equal. The degrees of the four angles added together equal 180. read more

To find the rotational symmetry first of all it is necessary to learn about rotational symmetry. If we rotate any shape in such a way that, we get exactly same Position of that shape, then it is called rotational symmetry. In Geometry, the rotational symmetry order entirely depends on equal number of sides. read more
