A **quadrant** is each of the four equal parts that the Cartesian axes divide the plane into.

### First Quadrant

The **first quadrant** is between **0º** and **90º**.

#### Sign

Quadrant | Abscissa | Ordinate |
---|---|---|

First | + | + |

#### Examples

The points A = (1, 2), B = (2, 4) C = (3, 5) and D = (5, 1) are in the first quadrant.

### Second Quadrant

The **second quadrant** is between **90º** and **180º**.

#### Sign

Quadrant | Abscissa | Ordinate |
---|---|---|

Second | − | + |

#### Examples

The points A = (−1, 2), B = (−2, 4) C = (−3, 5) and D = (−5, 1) are in the second quadrant.

### Third Quadrant

The **third quadrant** is between **180º** and **270º**.

#### Sign

Quadrant | Abscissa | Ordinate |
---|---|---|

Third | − | − |

#### Examples

The points A = (−1, −2), B = (−2, −4) C = (−3, −5) and D = (−5, −1) are in the third quadrant.

### Fourth Quadrant

The **fourth quadrant** is between **270º** and **360º**.

#### Sign

Quadrant | Abscissa | Ordinate |
---|---|---|

Fourth | + | − |

#### Examples

The points A = (1, −2), B = (2, −4) C = (3, −5) and D = (5, −1) are in the fourth quadrant.
