An acute angle is that which is less than a right angle. XIII. " A term or boundary is the extremity of any thing.
Σελίδα 8 - When a straight line standing on another straight line, makes the adjacent angles equal to one another, each of the angles is called a, right angle ; and the straight line which stands on the other is called a perpendicular to it. 11.
