Page 280 - All the interior angles of any rectilineal figure, together with four right angles, are equal to twice as many right angles as the figure has sides.

Page 32 - Place the numbers so that those of the same denomination may stand directly under each other.
Page 11 - Subtract the subtrahend from the dividend, and to the remainder bring down the next period for a new dividend, with which proceed as before ; and so on, till the whole is finished.
Page 297 - Hence, conversely, a line drawn perpendicular to a tangent, at the point of contact, passes through the centre of the circle.
Page 264 - A Right angle is that which is made by one line perpendicular to another. Or when the angles on each side are equal to one another, they are right angles.
Page 325 - Similar solid figures are such as have all their solid angles equal, each to each, and are contained by the same number of similar planes.
Page 275 - THE Difference of any Two Sides of a Triangle, is Less than the Third Side.
