Question

what are the properties we need to prove a quadrilateral a-:. 1)Square 2)Rectangle. 3)Rhombus. 2)Parallelogram.​

Answer 1

Square

1-All interior angles should be 90 degree.

2-All lines should be equal.

Rectangle

1-1pair of opposite side should be parallel and equal

Rhombus

1- All sides should be equal.

Parallelogram

1-1pair of opposite side should be parallel and equal

Answer 2

• Every quadrilateral has 4 vertices, 4 angles, and 4 sides.

• The total of its interior angles = 360 degrees.

• A quadrilateral with four equal sides and four right angles is a square.

• A quadrilateral that has opposite sides equal and measure of every angle is 90 degrees is a rectangle.

• Parallelogram, trapezium, rhombus, and kite are other examples of quadrilaterals.
