## Types of trianglesÂ

### Types of triangles (EMCHZ)

Name | Diagram | Properties |

Scalene | All sides and angles are different. | |

Isosceles | Two sides are equal in length. The angles opposite the equal sides are also equal. | |

Equilateral | All three sides are equal in length and all three angles are equal. | |

Acute-angled | Each of the three interior angles is less than 9090Â°. | |

Obtuse-angled | One interior angle is greater than 9090Â°. | |

Right-angled | One interior angle is 9090Â°. |

### The mid-point theorem (EMCJ7)

The line joining the mid-points of two sides of a triangle is parallel to the third side and equal to half the length of the third side.
