Monster Thinks

The new CBSE Syllabus of CBSE Class 10 Maths for the academic session 2022-2023. Also, check the deleted portion of the syllabus that will not be assessed in the CBSE Class 10 Maths Board Exam 2023.

CBSE Class 10 Maths Syllabus for the academic session 2022-2023 is provided here for students to know the latest course structure assigned per the annual assessment scheme. The board has terminated the term-wise assessment policy for the new academic session. Students must go through the latest CBSE Class 10 Maths Syllabus to know the chapters and topics to be covered during the year. We have also prepared the list of chapter-wise topics that are not a part of the new syllabus and will not be assessed in the CBSE Board Exam 2023.

## UNIT IV: GEOMETRY

1. TRIANGLES (15 Periods)

Definitions, examples, and 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 line is parallel to the third side.

(Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles 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.

2. CIRCLES (10 Periods)

Tangent to a circle at, the point of contact

(Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.

(Prove) The lengths of tangents drawn from an external point to a circle are equal.
