If a quadrilateral is a square, then the quadrilateral is a rectangle.

Proved that if a quadrilateral is a square then the quadrilateral is also a rectangle.Explain quadrilaterals.A quadrilateral is a closed shape created by uniting four points, any three of which cannot be collinear. Four sides, four angles, and four vertices make up a quadrilateral.Quadrilaterals have a few characteristics. The list is as follows.Each side has four sides.Each of them has four vertices.Two diagonals are present.360 degrees is the sum of all interior angles.Given, to prove if a quadrilateral is a square, then the quadrilateral is a rectangle.Square has four equal sides, and all the four angles are right angled.Rectangle has equal opposite sides, and all four angles are right angle.Here, the two sides of square can be increased to form a rectangle.Hence, proved that if a quadrilateral is a square then the quadrilateral is also a rectangle.To know more about quadrilaterals, visit:https://brainly.in/question/21343216#SPJ1
