Question

Name all parts of a quadrilateral.

Answer 1

Hint: This kind of problem requires no formula. You just have to use a little logic. Start the solution by defining what exactly is a quadrilateral. Construct a diagram of a quadrilateral. After this step write down the ways of writing the names of vertices, edges and angles as asked in the question.

Complete step-by-step answer:
A quadrilateral is a geometric two dimensional shape which is closed by four straight sides. It is recognized by it’s four vertices or corners and four edges.
We will take help of the following diagram of a quadrilateral to further understand all it’s parts.

The four vertices or corners of the quadrilateral are named using capital letters. They are usually named sequentially i.e. clockwise or anticlockwise.
The four edges or sides of the quadrilateral are denoted as following:
 $ \overline {{\text{AB}}} ,\overline {{\text{BC}}} ,\overline {{\text{CD}}} ,\overline {{\text{AD}}} $
Also each pair of adjacent sides will form an angle. Hence four angles will be formed. We have to name this angles as follows:
 $ \angle {\text{A,}}\angle {\text{B,}}\angle {\text{C,}}\angle {\text{D}} $ respectively. $ \square {\text{ABCD}} $
At last the general way of representing a quadrilateral is $ \square {\text{ABCD}} $ which is in sequential order.

Note: A quadrilateral can be of different shape and size which are named differently on the basis of their different properties. But what remains common are the properties as mentioned above. Any quadrilateral be it of any type can be named according to the pattern mentioned above. This is the general way of naming the parts of the quadrilateral.
