<p>To solve the question, "A parallelogram in which both the diagonals are equal and bisect each other is a:", we can follow these steps:</p><p>1. <strong>Understand the Properties of Parallelograms</strong>: - A parallelogram is a quadrilateral with
AE and BC are equal, and are parallel because the angles at A and B are both equal to 90° (allied angles, converse). Hence ABCE is a parallelogram (opposite sides equal and parallel). so that EC and AB are equal (property of a parallelogram).It follows that ABCE is a square (a ...
解析 A。选项 A“square”是正方形,有四条相等的边和四个直角;选项 B“parallelogram”是平行四边形,对边相等;选项 C“rhombus”是菱形,四条边相等但不一定有直角;选项 D“trapezoid”是梯形,四条边不一定相等也不一定有直角。所以答案是 square。反馈 收藏 ...
