сЕКъДА 307 - If two triangles have two angles of the one equal to two angles of the other, each to each, and one side equal to one side, viz. either the sides adjacent to the equal...
сЕКъДА 319 - Triangles upon the same base, and between the same parallels, are equal to one another.
сЕКъДА 300 - Any two sides of a triangle are together greater than the third side.
сЕКъДА 326 - To a given straight line to apply a parallelogram, which shall be equal to a given triangle, and have one of its angles equal to a given rectilineal angle.
сЕКъДА 312 - If a straight line fall on two parallel straight lines, it makes the alternate angles equal to one another,and the exterior angle equal to the interior and opposite angle on the same side ; and also the two interior angles on the same side together equal to two right angles.
сЕКъДА 332 - In any right-angled triangle, the square which is described upon the side subtending the right angle, is equal to the squares described upon the sides which contain the right angle.
сЕКъДА 283 - If two angles of a triangle be equal to one another, the sides also which subtend, or are opposite to, the equal angles, shall be equal to one another.
сЕКъДА 314 - 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.
сЕКъДА 279 - THE angles at the base of an isosceles triangle are equal to one another : and, if the equal sides be produced, the angles upon the other side of the base shall be equal.
сЕКъДА 268 - A circle is a plane figure contained by one line, which is called the circumference, and is such that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
