Q. Is a quadrilateral always a parallelogram?Choices:(A) yes(B) no
Define quadrilateral: Step 1: Define a quadrilateral.A quadrilateral is any four-sided figure. It includes various shapes like squares, rectangles, trapezoids, and parallelograms.
Define parallelogram: Step 2: Define a parallelogram.A parallelogram is a specific type of quadrilateral where opposite sides are parallel and equal in length.
Compare properties: Step 3: Compare properties.Not all quadrilaterals have opposite sides that are parallel and equal. For example, a trapezoid has only one pair of parallel sides, which disqualifies it from being a parallelogram.
Conclusion: Step 4: Conclusion based on properties.Since some quadrilaterals like trapezoids do not meet the criteria for parallelograms, it's clear that not all quadrilaterals are parallelograms.
