Take F the centre of the circle ABCD : And , first , let the segment BAED be
greater than a semicircle , and join BF , FD : And because the angle BFD is at the
centre , and the angle Bad at the circumference , and that they have the same
part of ...

F In a circle , the angle in a semicircle is a right angle ; but the angle in a segment
greater than a semicircle is less than a right angle ; and the angle in a segment
less than a semicircle is greater than a right angle . Let ABCD be a circle , of ...

Side 17 - Any two angles of a triangle are together less than two right angles. Let ABC be any triangle ; any two of its angles together are less than two right angles.
Side 84 - IF from a point without a circle there be drawn two straight lines, one of which cuts the circle, and the other meets it; if the rectangle contained by the whole line which cuts the circle, and the part of it without the circle, be equal to the square of the line which meets it, the line which meets it shall touch the circle.
Side 82 - If from any point without a circle two straight lines be drawn, one of -which cuts the circle, and the other touches it; the rectangle contained by the whole line which cuts the circle, and the part of it without the circle, shall be equal to the square of the line which touches it.
Side 11 - UPON the same base, and on the same side of it, there cannot be two triangles that have their sides which are terminated in one extremity of the base equal to one another, and likewise those which are terminated in the other extremity.

Side 7 - From the greater of two given straight lines to cut off a part equal to the less. Let AB and C be the two given straight lines, whereof AB is the greater.
