π Motivation for studying Arithmetic Progression Derivation of the nth term and sum of the first n terms of A.P. and their application in solving daily life problems.
GEOMETRY 15
TRIANGLES
π Definitions, examples, counter examples of similar triangles.
π (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.
π (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.
π (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
π (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
π (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.

π Tangent to a circle at, point of contact
π (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.
π (Prove) The lengths of tangents drawn from an external point to a circle are equal.
