A quadrilateral is a polygon with four sides. Another name for quadrilateral ABCD is ADCB.
What is a quadrilateral?
A four-sided polygon with four edges and four corners is known as a quadrilateral. The name comes from the Latin words Quadri, which means "four," and latus, which means "side."
As we know that in order to name a polygon the letters should be always end-to-end connected, therefore, letters can't be chosen randomly.
For example, if there is a quadrilateral as shown below in the image then it can be named PQRS or PSRQ. Therefore, the letters should be consecutive to each other.
Hence, the other name for quadrilateral ABCD is ADCB.
