![]() In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.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.Proofs of the following theorems are deleted: Simple problems on equations reducible to linear equations. PAIR OF LINEAR EQUATIONS IN TWO VARIABLES Statement and simple problems on division algorithm for polynomials with real coefficients. Theorem Triangle Angle Bisector Theorem -If a ray bisects an angle of a triangle, then it divides the opposite side on the triangle into two segments that are proportional to the other two sides of the triangle.CBSE Class 10 Maths Deleted Syllabus 2023-2024ĬBSE Class 10 Maths Deleted Syllabus 2023-24: Check complete list of chapter-wise topics removed from the syllabus below:ĭecimal representation of rational numbers in terms of terminating/non-terminating recurring decimals. Theorem If three parallel lines intersect two transversals, then the segments intercepted are proportional. You can either use or T x 5 S U 16 10 R V Similarity in Triangles Side Splitter Theorem - If a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally.
