Isosceles trapezoid
A normal trapezoid with at least 25 square feet.
A right trapezoid has at least two right angles.
No. A trapezoid need not have any right angles.
No. A quadrilateral is trapezoid if it has at least one pair of parallel sides.
It is an isosceles triangle and an isosceles trapezoid
No.

A Trapezoid.
Yes, an isosceles trapezoid can have at least one right angle. In such a trapezoid, the non-parallel sides are equal in length, and if one of the angles between a base and a non-parallel side is a right angle, the trapezoid will still maintain its isosceles properties. This configuration results in a trapezoid that is both isosceles and contains a right angle.
