How to Make Triangles

Triangles are a part of math, art, and other everyday things.

A triangle is a geometric shape that contains three sides and three angles. There are three different types of triangles: equilateral, isosceles and scalene. The sides and angles can all be equal but they can also be of all different measurements. Depending for what you plan to use the triangle, making one will have a different method. Making a triangle can be done with several styles of drawing, and by using other mediums.

Things You'll Need

• Drawing or writing utensil or paint and paintbrush
• Graphic design or photo editing software
• Scissors
• Paper

Instructions

1. Draw a triangle with a pen, pencil, crayon, paint and paintbrush or other writing or drawing utensil. Create three lines on paper. Both ends of each line must connect to the end of another line to create three angles.

2. Make a triangle in graphic design or photo editing software such as Adobe Illustrator, Microsoft Paint, or Adobe Photoshop. Select the pen, pencil or paintbrush tool from the tools palette, and then click any point on the workspace. Hold the mouse button down and drag the cursor to create a line. Repeat this process to create two more lines. The ends of the lines must touch to create three angles.

3. Cut out a paper triangle with a pair of scissors. Create the sides of the triangle by cutting edges that all connect to a point that creates three angles.
