# Basic Geometry

### Example 1

Find the missing side of this triangle. | The length of the hypotenuse is missing, and we are given the lengths of the legs. |

### Example 2

Find the length of the missing side of this right triangle. | The length of a leg is missing, and we are given the lengths of the other leg and the hypotenuse. |

### Example 3

Is a triangle with sides lengths of 4 cm, 7 cm, and 8 cm a right triangle? | If it is a right triangle, then the sum of the squares of the two smaller sides will equal the square of the largest side. |
