UNIT IV: GEOMETRY

1. TRIANGLES (15) Periods
   Definitions, examples, counter examples of similar triangles.
   1. (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.
   2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.
   3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
   4. (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
   5. (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.
2. CIRCLES (10) Periods
   Tangent to a circle at, point of contact
   1. (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.
   2. (Prove) The lengths of tangents drawn from an external point to a circle are equal.

UNIT V: TRIGONOMETRY

1. INTRODUCTION TO TRIGONOMETRY (10) Periods
