# How to Graph Triangles and Quadrilaterals?

You can easily draw triangles and quadrilaterals on the coordinate plane. Join us in this post to learn how to graph triangles and quadrilaterals.

**Step by Step guide to graphing triangles and quadrilaterals**

It is better to get familiar with triangles and quadrilaterals before graphing them:

**What is a triangle?**

A triangle is a simple polygon with \(3\) sides and \(3\) interior angles. It is one of the basic shapes in geometry in which \(3\) vertices are connected and denoted by a symbol \(△\).

**What is a** **quadrilateral? **

A quadrilateral is a polygon with four sides, four angles, and four vertices. Whenever we name a quadrilateral, we must consider the order of the vertices.

**How to graph triangles and quadrilaterals?**

The following steps will be useful to graph triangles and quadrilaterals on the coordinate plane:

**1.** Mark the given points on the graph sheet one by one.

- \((x, y) \rightarrow\) Choose the first quadrant
- \((-x, y) \rightarrow\) Choose the second quadrant
- \((-x, -y)\rightarrow\) Choose the third quadrant
- \((x, -y) \rightarrow\) Choose the fourth quadrant

**2.** Join the marked points.

**3.** Name the vertices.

**Graphing Triangles and Quadrilaterals** **– Example 1:**

Graph the triangle with vertices \((2, -3)\), \((-6, -7)\) and \((-8, -3)\).

**Solution:**

\((2, -3)\rightarrow (x, -y)\rightarrow\) lies in the fourth quadrant

\((-6, -7)\rightarrow (-x, -y) \rightarrow\) lies in the third quadrant

\((-8, -3) \rightarrow (-x, -y)\rightarrow\) lies in the third quadrant

By plotting the given points, we got above triangle \(ABC\).
