Side 128 - The area of a rectangle is equal to the product of its base and altitude.
Side 348 - Three lines are in harmonical proportion, when the first is to the third, as the difference between the first and second, is to the difference between the second and third ; and the second is called a harmonic mean between the first and third. The expression 'harmonical proportion...
Side 19 - The perpendicular is the shortest line that can be drawn from a point to a straight line.
Side 79 - To draw a straight line through a given point parallel to a given straight line. Let A be the given point, and BC the given straight line ; it is required to draw a straight line through the point A, parallel to the straight hue BC.
Side 29 - The sum of the three angles of any triangle is equal to two right angles.
Side 175 - If a straight line is perpendicular to each of two straight lines at' their point of intersection, it is perpendicular to the plane of those lines.
Side 263 - The sum of the angles of a spherical triangle is greater than two and less than six right angles ; that is, greater than 180° and less than 540°. (gr). If A'B'C' is the polar triangle of ABC...
Side 219 - A truncated triangular prism is equivalent to the sum of three pyramids, whose common base is the base of the prism and whose vertices are the three vertices of the inclined section.
Side 197 - A right prism is a prism •whose lateral edges are perpendicular to the planes of the bases.
Side 127 - Any two rectangles are to each other as the products of their bases by their altitudes. Let R and R...
