To cut a right-angled triangle from a square piece of paper is not difficult. To cut a equilateral triangle is a little more of a challenge, though.
Do you have an origami project that calls for a triangle instead of a square? Or a mathematics project, maybe? No fear, this article holds the solution!
Steps
-
Take your square of paper.
-
Fold it in half vertically to determine the mid-line. Unfold.
-
Measure the bottom side of the square. In this case, it is 146 mm.
-
Memorize this measurement. Take your ruler and lay the point of the measurement on the bottom corner of the square. Angle the ruler so that the "0" point falls on the mid-line.
-
Draw a line with the ruler and pencil.
-
Repeat the previous two steps for the other side of the triangle.
-
Cut out on your pencil lines.
-
Finished.
Tips
- Always double-check your measurements before drawing the pencil line or cutting out the triangle.
