From this it is manifest that the straight line which is drawn at right angles to the
diameter of a circle from the extremity of it , touches the circle ; and that it touches
it only in one point , because , if it did meet the circle in two , it would fall within it ...

Therefore the angle EBA is equal to the angle EDF : But EDF is a right angle ,
wherefore EBA is a right angle : And EB is drawn from the centre : but a straight
line drawn from the extremity of a diameter , at right angles to it , touches the
circle ...

If a straight line touches a circle , and from the point of contact a straight line be
drawn at right angles to the touching line , the centre of the circle shall be in that
line . Let the straight line DE touch the circle ABC in • c , and from c let ca be
drawn ...

If a straight line touches a circle , and from the point of contact a straight line be
drawn cutting the circle , the angles made by this line with the line touching the
circle , shall be equal to the angles which are in the alternate segments of the
circle ...

Let any point d be taken without the circle ABC , and from it let two straight lines
DCA and DB be drawn , of which DCA cuts the circle , and DB meets it ; if the
rectangle AD , DC be equal to the square of DB ; DB touches the circle . Draw (

Side 30 - Parallelograms upon equal bases, and between the same parallels, are equal to one another.
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 19 - To make a triangle of which the sides shall be equal to three given straight lines, but any two whatever of these must be greater than the third, (i.
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.
