Question | Answer |

The perimeter of a polygon is | the measure of the distance around the polygon. |

Circumference is | the distance around or perimeter of a circle. |

The area of a closed curve is the | number of nonoverlapping square units required to fill the region enclosed by the curve. |

The perimeter of a square whose side measures x | is 4 times x (P = 4x) |

The area of a square whose side is "x", | is side times side (A = x^2). |

The perimeter of a rectangle | is the sum of twice the length and twice the width [P = 2l + 2w, or |

P = 2(l + w)]. | Is the formula for perimeter of a rectangle. |

A rectangle's area | is the product of the length and the width (A = lw). |

The value of pi | is the ratio of the circumference of a circle to its diameter. |

The ratio of the circumference to the diameter of a circle is a constant value, | pi. |

The fractional approximation of pi | is 22/7 . |

The decimal approximation of pi | is 3.14. |

The circumference of a circle | is computed using or d*pi or 2pi*r , where d is the diameter and r is the radius of the circle. |

The area of a circle | is computed using the formula, pi*r^2 , where r is the radius of the circle. |

The surface area of a rectangular prism | is the sum of the areas of all six faces. |

The volume of a rectangular prism | is computed by multiplying the area of the base, B, (length x width) by the height of the prism. |

1 inch | is about 2.5 centimeters. |

1 foot | is about 30 centimeters. |

1 meter | is a little longer than a yard, or about 40 inches. |

1 mile | is slightly farther than 1.5 kilometers. |

1 kilometer | is slightly farther than half a mile. |

1 ounce is about | 28 grams. |

1 nickel | has the mass of about 5 grams. |

1 kilogram | is a little more than 2 pounds. |

1 quart | is a little less than 1 liter. |

1 liter | is a little more than 1 quart. |

Water freezes | at 0°C and 32°F. |

Water boils | at 100°C and 212°F. |

Normal body temperature | is about 37°C and 98°F. |

Room temperature | is about 20°C and 70°F |

Congruent figures | have exactly the same size and the same shape. |

Noncongruent figures may have | the same shape but not the same size. |

The corresponding angles of congruent polygons have | the same measure, and the corresponding sides of congruent polygons have the same measure. |

The determination of the congruence or noncongruence of two figures can be accomplished by | placing one figure on top of the other or by comparing the measurements of all sides and angles. |

A quadrilateral | is a closed planar (two-dimensional) figure with four sides that are line segments. |

A parallelogram | is a quadrilateral whose opposite sides are parallel and opposite angles are congruent. |

A rectangle | is a parallelogram with four right angles. |

Rectangles have special characteristics | (such as diagonals are bisectors) that are true for any rectangle. |

To bisect means | to divide into two equal parts. |

A square | is a rectangle with four congruent sides or a rhombus with four right angles. |

A rhombus | is a parallelogram with four congruent sides. |

A trapezoid | is a quadrilateral with exactly one pair of parallel sides. |

The parallel sides of a trapezoid | are called bases, and the nonparallel sides are called legs. |

An iscoles trapezoid | is If the legs have the same length, then the trapezoid. |

A kite | is a quadrilateral with two pairs of adjacent congruent sides. One pair of opposite angles is congruent. |

Quadrilaterals can be sorted according to | common attributes, using a variety of materials. |

a parallelogram, rectangle, rhombus, and square each have | two pairs of parallel sides; |

a trapezoid | has only one pair of parallel sides; other quadrilaterals have two pairs of parallel sides. |

a rectangle has | four 90° angles; |

a trapezoid may have | zero or two 90° angles. |

A square is a special type of both | a rectangle and a rhombus, |

The sum of the measures of the angles of a quadrilateral | is 360°. |

A kite | has two pairs of congruent, adjacent sides. The two pairs are not congruent to each other. |
