Page 106 - Thus a parabola is the locus of a point which moves so that its distance from a fixed point is equal to its distance from a fixed straight line (see fig.
Page 659 - A Cone is a solid figure, described by the revolution of a right.angled triangle about one of the sides containing the right angle, which side remains fixed.
Page 657 - A STRAIGHT line is perpendicular to a plane, when it is perpendicular to every straight line which it meets in that plane.
Page 36 - Prove that parallelograms on the same base and between the same parallels are equal in area.
Page 184 - The projection of a point on a plane is the foot of the perpendicular let fall from the point to the plane.
Page 52 - From a given circle to cut off" a segment, which shall contain an angle equal to a given rectilineal angle.
Page 101 - The locus of a point which moves in a plane in such a way that the ratio of its distance from a fixed point to its distance from a fixed line is constant is called a conic.
Page 660 - If a straight line is perpendicular to each of two other straight lines at their point of intersection, it is perpendicular to the plane of the two lines.
