#ch6ncert qus with example #10th mathh #10math #ncert Triangles in Class 10 mathematics form a fundamental chapter focusing on their properties, types, similarity criteria, and theorems like Basic Proportionality and Pythagoras. This builds on basic geometry to solve problems involving proportions and proofs.��Key PropertiesAngle Sum Property: The sum of interior angles in any triangle is always 180°.��Triangle Inequality Theorem: The sum of any two sides exceeds the third side; the difference of two sides is less than the third.��Exterior Angle Property: An exterior angle equals the sum of the two opposite interior angles.��Larger angle is opposite the longer side; equal sides imply equal opposite angles.��Types of TrianglesSimilarity CriteriaTriangles are similar if they match by AA (two angles), SSS (three sides proportional), or SAS (two sides proportional with included angle).��Main TheoremsBasic Proportionality (Thales'): A line parallel to one side divides the other two proportionally.�Pythagoras Theorem: In a right triangle, [a^2 + b^2 = c^2] (c hypotenuse).��
