Move any of the two large points (below) anywhere you'd like at any time.
Slide the black slider to form an isosceles right triangle.
Then, answer the questions that follow.

## 1.

Use the **Angle** tool to measure and display the measures of angles *A* and *B*. What is each angle measure?

## 2.

Suppose *AB* = 10 cm. Determine the length of the hypotenuse AC.

## 3.

Suppose **hypotenuse** A*C* = 4 cm. Determine the length of leg AB.

## 4.

Suppose *AB* = 5 cm. What is the length of BC?

## 5.

Suppose *AB* = 6 cm. Determine the length of the hypotenuse AC.

## 6.

Suppose *AB* = cm. Determine the length of the hypotenuse AC.

## 7.

Suppose hypotenuse *AC* = cm. Determine the length of the leg BC in its **most** simplified radical form.
