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

polygon | a closed figure made from segments that are drawn on a flat surface and do not cross. A polygon can have3 or more sides. Some types of polygons are: pentagons (5 sides), hexagons (6 sides), octagons (8. sides), decagons (10 sides), etc. |

parallel lines | lines on a flat surface that do not meet |

quadrilateral | a polygon with four sides |

trapezoid | a quadrilateral with exactly one pair of parallel sides |

parallelogram | a quadrilateral with two pairs of parallel sides |

rhombus | a parallelogram with all sides the same length |

regular polygon | a polygon that has sides that are all of equal length and angles that are all of equal measure |

congruent | having the same size and shape |

line symmetry | a figure has line symmetry when it can be folded in half so that the two halves fit exactly on each other. The fold line is called the line of symmetry |

fraction | a number that compares a part with a whole |

numerator | the top number in a fraction that tells how many parts of the whole to consider |

denominator | the bottom number in a fraction that tells how many equal-sized parts the whole is divided into |

mixed number | the sum of a whole number and a fraction |

equivalent fractions | fractions that name the same part of a whole |

lowest terms | a fraction is in lowest terms when 1 is the greatest whole number that will divide both the numerator and the denominator evenly |

translation | a change made to a figure by sliding every point of it the same distance in the same direction |

rotation | a change made to a figure by turning it around a fixed point. The point of rotation can be any fixed point outside, inside, or on the figure |

reflection | a change made to a figure by flipping it across a line |

transformation | a change made to a figure or its position |

decimal system | a system of numbers based on 10 |

place value | the numerical value assigned to the different positions of digits in a number that is written in decimal form |

equivalent decimals | two decimals that represent the same amount |
