Answer 1

Answer: (A) rectangle

Step-by-step explanation:

➡️ Rectangle has opposite sides parallel

➡️ It has opposite sides equal

➡️ Rectangle is a parallelogram

➡️ Its angles at vertices are 90 degree

➡️ So it is a parallelogram with angle at vertices as 90 degree

Answer 2

A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.
