Side 5 - The circumference of every circle is supposed to be divided into...
Side 48 - UPON a given straight line to describe a segment of a circle containing an angle equal to a given rectilineal angle.
Side 3 - A plane rectilineal angle is the inclination of two straight lines to one another, which meet together, but are not in the same straight line.
Side 39 - Parallelograms on the same base, and between the same parallels, are equal to one another.
Side 59 - Quadrilateral ; of five sides a Pentagon ; of six sides a Hexagon ; of seven sides a Heptagon ; of eight sides an Octagon ; of nine sides a Nonagon ; of ten sides a Decagon ; of twelve sides a Dodecagon.
Side 112 - Polygons are those which have more than four sides. They receive particular names from the number of their sides ; thus a pentagon has five sides, a hexagon has six sides, a heptagon seven, an octagon eight, a nonagon nine, a decagon ten, an undecagon eleven, and a dodecagon has twelve sides.
Side 118 - Divide the area by . 7854 and extract the square root of the quotient.
Side 82 - To rearrange an equation you can • add the same quantity to both sides • subtract the same quantity from both sides • multiply both sides by the same quantity • divide both sides by the same quantity.
Side 107 - Find the area of a field in the form of a trapezoid whose altitude is 120 m and whose parallel sides are 130 m and 180 m.
Side 4 - It is a line every point of which is at the same distance from a point within it called the centre.
