Σελίδα 175 - Two triangles having an angle of the one equal to an angle of the other are to each other as the products of the sides including the equal angles.
Σελίδα 113 - IF a side of any triangle be produced, the exterior angle is equal to the two interior and opposite angles ; and the three interior angles of every triangle are equal to two right angles.
Σελίδα 173 - The area of a circle is equal to one-half the product of its circumference and radius.
Σελίδα 33 - If two sides of a triangle are unequal, the angles opposite are unequal, and the greater angle is opposite the greater side.
Σελίδα 35 - In two polar triangles each angle of the one is the supplement of the opposite side in the other. Let ABC, A'B'C
Σελίδα 125 - After remarking that the mathematician positively knows that the sum of the three angles of a triangle is equal to two right angles...
Σελίδα 188 - It follows that the ratio of the circumference of a circle to its diameter is the same for all circles.
Σελίδα 147 - An oblique prism is equivalent to a right prism whose base is a right section of the oblique prism, and whose altitude is equal to a lateral edge of the oblique prism. Hyp. OM is a right section of oblique prism AD', and OM ' a right prism whose altitude is equal to a lateral edge of AD'. To prove AD' =0= GM' . Proof. The lateral edges of GM
