_{Quadrilaterals}

with some notes and quizzes

Curves

Curve: A figure formed on a plane surface by joining a number of points without lifting a pencil is called a curve.

Open Curve: A curve which does not end at the same starting point or which does not cut itself is called an open curve.

Closed Curve: A curve which cut itself or which starts and ends at the same point is called a closed curve.

Simple Closed Curve: A closed curve called a simple closed curve which does not intersect itself.
