How to Form a Perfect Right Angle Using Just String

There are certain challenges in life that seem easy, but in fact aren't. Like the brain teaser on how to form a perfect right angle using just string. This is a great activity to teach children about angles (think geometry) as well as getting them to be resourceful in problem solving.

Things You'll Need

• String
• Scotch tape (optional)

Instructions

1. Look for an object that has a right angle within it. As you look around almost any room, you'll find them all over the place, such as the seat of a chair, the end of a table, the corner of the room, or a dollar bill. Any square object, and most rectangles in practical use, has four right angles, which are at each corner of the object.

2. Lay the string along one side of the object. Stop laying the string at the corner of the object.

3. Bend the string along the other end of the object. Because you are working with string, which tends to flop around easily, you may want to place a piece of tape on the corner where you are bending the string. This will keep it in place.

4. Tighten each side of the string so that the place where the string changes directions comes to a perfect point and mimics the square object you are tracing. This completes your right angle using just string.
