Question

1) Origami paper is always in the shape of a square. If you take the top corner of either side of an 8.5 x 11-inch piece of paper and fold it to the lower opposite side and trim off the excess paper, this creates the square
that we need. Then fold the top corner to the opposite corner to create a diagonal, which is a typical first step to most origami designs.

What are the dimensions of your paper square? What is the length of the diagonal? Write your answer in exact form (with a radical) and decimal form.
Hint: Use the “Insert Math Equation” tool in the toolbar to insert your answer as a radical.

1. The dimensions of the paper square that can be used is 5cm by 5cm.

### How to illustrate the information?

It should be noted that a square simply means the shape that has all its sides to be equal.
In this case, the dimensions of the paper square that can be used is 5cm by 5cm.
It should be noted that based on the above information, the length of the diagonal is the hypothenuse. This will be:
= ✓5² + ✓5²
= ✓25 + ✓25
= ✓50
= ✓25 × ✓2
= 5✓2
Therefore, the length of the diagonal is 5✓2.
