УелЯдб 30 - ... if a straight line, &c. QED PROPOSITION 29. — Theorem. If a straight line fall upon two parallel straight lines, it makes the alternate angles equal to one another ; and the exterior angle equal to the interior and opposite upon the same side ; and likewise the two interior angles upon the same side together equal to two right angles.
УелЯдб 333 - The first of four magnitudes is said to have the same ratio to the second which the third has to the fourth, when any...
УелЯдб 294 - If a straight line meets two straight lines, so as to " make the two interior angles on the same side of it taken " together less than two right angles...
УелЯдб 10 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
УелЯдб 137 - Componendo, by composition ; when there are four proportionals, and it is inferred that the first together with the second, is to the second, as the third together with the fourth, is to the fourth.
УелЯдб 84 - The angle at the centre of a circle is double of the angle at the circumference upon the same base, that is, upon the same part of the circumference.
УелЯдб 292 - Thus, for" example, he to whom the geometrical proposition, that the angles of a triangle are together equal to two right angles...
УелЯдб 93 - UPON a given straight line to describe a segment of a circle containing an angle equal to a given rectilineal angle.
УелЯдб 38 - 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.
УелЯдб 58 - The rectangle contained by the sum and difference of two straight lines is equivalent to the difference of the squares of these lines.
