Question

Write the summary of quadrilateral properties.

Answer 1

Explanation.

• The interior angle of a concave quadrilateral is greater than one eighty degrees, and two diagonals fall outside the quadrilateral. For example, Dort.
• The interior angle of a convex quadrilateral is less than $180°$, and two diagonals lie within the quadrilateral.
• The shapes of elementary geometry are invariably convex.
• The square is a quadrilateral where all four sides are equal but in equivalent conditions opposite sides are equal.
• In an irregular quadrilateral, no sides are parallel to each other.
• In Trapezium at least one pair of opposite sides is parallel.
• A parallelogram is a quadrilateral comprising two pairs of parallel sides. They are of equal length in the equivalent condition.
• In the rhombus all sides are equal but diagonals may perpendicularly bisect each other at an equivalent condition.
• In kite two pairs of adjacent sides are of equal length.
