Simple situational problems may be included, Simple problems on equations reducible to linear equation may be included.

• Definitions, examples counter examples of similar triangles
• (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.
• (Motivate) : If a line divides two sides of a triangle in the same ratio, the lines is parallel to third side
• (Motivate): If in two triangles the corresponding angles are equal, their corresponding sides are proportional and the triangle are similar.
• (Motivate): If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
• (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.
• (Motivate): If a perpendicular is drawn from the vertex of the right angle to the hypotenuse, the triangle on each side of the perpendicular are similar to the whole triangle and to each other.
• (Prove): The ratio of the areas of two similar triangles is equal to the ratios of the squares on their corresponding sides.
• (Prove): In a right triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides.
• (Prove): In a triangle if the square on one side is equal to sum of the squares on the two sides, the angles opposite to the first side is a right triangle.

• Tangents to a circle motivated by chords drawn from points coming closer and closer to the point.
• Prove: The tangent at any point of a circle is perpendicular to the radius through the point of contact.
