• Three or more points lying on the same line are called collinear points otherwise they are non-collinear points.

• The length of a tangent to a circle is measured from the given point to the point of contact.
• If a line is drawn perpendicular to a radial segment of a circle at its outer end point, it is tangent to the circle at that point.
• The tangent to a circle and the radial segment joining the point of contact and the centre are perpendicular to each other.
• Second degree equation:  A second degree equation in one variable x, is ax² + bx + c = 0, a ≠ 0 and a, b, c are constants is called the general or standard form of a quadratic equation. Where a is the co-efficient of x², b is the co-efficient of x and constant term is c.
• In any triangle, the sum of the squares on any two sides is equal to twice the square on half the third side together with twice the square on the median which bisects the third side (Apollonius' Theorem).
• The projection of a given point on a line segment is the foot of ⊥ drawn from the point on that line segment. If CD ⊥ AB, then evidently D is the foot of perpendicular CD from the point C on the line segment AB.
