**number 22 of chapter 2.4 on page 80**.

The hypotenuse of an

**isosceles right triangle**has a length of

**20 cm**. What is the

**length**of each

**leg of the triangle**? Provide your answer to the nearest tenth of a centimetre.

**Isosceles Right Triangle:**a triangle with two equal side lengths.

**Conclusion:**

The triangle had a hypotenuse of 20 cm and so what I did was I used the formula c (squared) = a (squared) + a (squared) to get the length of a. Then I took 20 (squared) or 400 and divided it by 2 to get a (squared) by itself. So now we're left with square root of 200 = the square root of a (squared) to get a by itself. We then end up with 14.1 cm (rounded to the nearest tenths place) as the length of a.
