Creating a 45-degree angle without a protractor can be done quite easily using a few different methods. One of the most common ways is to use a simple square or a piece of paper.
Here’s a step-by-step method using a piece of paper:
- Take a standard A4 or letter-sized piece of paper.
- Fold the paper in half lengthwise so that the shorter edges meet. This will create a crease down the middle.
- Unfold the paper, and now you have a line that divides the sheet into two equal halves.
- Next, fold the paper diagonally from one corner to the opposite corner. When you do this, the crease will intersect the previous crease at a 90-degree angle.
- Now, when you unfold it again, you’ll see that the diagonal crease divides the right angle you created into two equal 45-degree angles.
Alternatively, if you have a right angle already defined, you can simply bisect it to get your 45-degree angle. This can be done by using a compass or even just visually estimating by drawing a line halfway between the two lines forming the right angle.
Using these simple techniques, you can easily create a 45-degree angle without needing a protractor!
