उन्होंने यह भी बताया है की फर्स्ट टर्म के एग्जाम नवंबर से दिसंबर के बीच में लिए जाएंगे और सेकंड टर्म के एग्जाम मार्च और अप्रैल के बीच में लिए जाएंगे नवंबर से दिसंबर के बीच में होने वाले एग्जाम में बच्चों के पास समय कम होने के कारण बोर्ड ने यह निर्णय लिया है कि उनके सिलेबस को भी कम किया जाएगा और फर्स्ट टर्म MCQ के होंगे जो कि 90 अंक परीक्षा की होगी।

LINES (In two-dimensions) :- Review: Concepts of coordinate geometry, graphs of linear equations. Distance formula. Section formula (internal division). Area of a triangle.


TRIANGLES :- 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.
  6. (Motivate) If a perpendicular is drawn from the vertex of the right angle of a right triangle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other.
  7. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.
  8. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
  9. (Prove) In a triangle, if the square on one side is equal to sum of the squares on the other two sides, the angles opposite to the first side is a right angle.

CIRCLES :- 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.
  3. (Motivate) Alternative Segment theorem: If a chord is drawn through the point of contact of a tangent to a circle, then the angles made by the chord with the tangent are respectively equal to the angles subtended by the chord in the alternate segments.


  1. Division of a line segment in a given ratio (internally).
  2. Tangents to a circle from a point outside it.
  3. Construction of a triangle similar to a given triangle.
