Side 128 - The angle at the centre of a circle is double the angle at the circumference on the same arc.
Side 26 - IF three straight lines be proportionals, the rectangle contained by the extremes is equal to the square of the mean ; and if the rectangle contained by the extremes be equal to the square of the mean, the three straight lines are proportionals.
Side 111 - In any triangle, the square of the side subtending an acute angle is less than the sum of the squares of the...
Side 4 - A straight line is said to be cut in extreme and mean ratio, when the whole is to the greater segment as the greater segment is to the less.
Side 98 - If a straight line be divided into any two parts, the square of the whole line is equal to the squares of the two parts, together with twice the rectangle contained by the parts.
Side 2 - Convertendo ; when it is .concluded, that if there be four magnitudes proportional, the first is to the sum or difference of the first and second, as the third is to the sum or difference of the third and fourth.
Side 20 - DE : but equal triangles on the same base and on the same side of it, are between the same parallels ; (i.
Side 116 - If any two points be taken in the circumference of a circle, the straight line which joins them shall fall within the circle.
Side 156 - The sum of the squares of the sides of any quadrilateral is equal to the sum of the squares of the diagonals plus four times the square of the line joining the middle points of the diagonals.
Side 28 - Similar triangles are to one another in the duplicate ratio of their homologous sides.
