# OGT Math Meas Triang

### OGT Math Measurement D Triangles

Question | Answer |
---|---|

The sum of the measure of the angles of a triangle always equals ____ degrees | 180 |

If angle A equals 50 degrees and B equals 55, what is the value of angle C? | 75 because 50 + 55 + C = 180 |

Equilateral Triangle | All three sides of equal length. |

Isosceles Triangle | At least two sides of equal length. |

Acute Triangle | All angles are acute (less than 90degrees) |

Obtuse Triangle | One obtuse angle (greater than 90degrees) |

Right Triangle | At least one right angle |

In a right triangle if one acute angel is 40 degrees, how much is the other? | 50 |

Each angle in an equilateral triangle is ___ degrees | 60 |

A triangle with no congruent sides is called ____ | scalene |

the side across from a right angle | HYPOTENUSE |

If a triangle has 2 congruent sides then it has ___ | 2 congruent angles |

If a triangle has 3 congruent angles then it has ___ | 3 congruent sides |

True or False If a triangle is obtuse then it will have an angle sum of 180 | True - all triangles have an angle sum of 180 |

The sum of the measure of the angles of a triangle always equals ___ degrees | 180 |

A ____ has At least two sides of equal length | Isosceles Triangle |

A ____ has All three sides of equal length. | Equilateral Triangle |

A ____ has All angles are acute (less than 90ￂﾰ) | Acute Triangle |

A(n) ____ has One obtuse angle (greater than 90ￂﾰ) | Obtuse Triangle |

A Right Triangle has at least one angle measuring ____ | 90 degrees |

The triangle ABC is an equilateral triangle. What is the measure of angle A? | 60 degrees |

In a right triangle, if one acute angle equals 64ￂﾰ, what is the value of the other? | 26 degrees |

In a triangle, A = 60ￂﾰ, B = 60ￂﾰ, and Z = 10 cm. What is the length of side X? | 10 cm (they are all the same length |

If a triangle has two equal sides then it also has ___ | 2 equal angles |

If angle A = C = 30 degrees. What type of triangle is it? | Isosceles (it has two equal angles so it must have 2 equal sides) |

If angle A equals 50ￂﾰ and B equals 55ￂﾰ, what is the value of the third angle of the triangle? | 75 degrees (the total is 180) |

In a triangle, what is the value of angle A + angle B + angle C? | 180 |

An isosceles triangle is a triangle with at least two _____ of equal length and at least two angles of equal measure | sides |
