(ASA Congruence). The comparison done in this case is between the sides and angles of the same triangle. Two triangles are congruent if the three sides of one triangle are equal to the corresponding three sides of the other triangle. If, ∠A = ∠D, ∠B = ∠E, ∠C = ∠F, then ΔABC ≈ ΔDEF, If the two sides of a triangle is in proportion with the corresponding two sides of the other triangle and the included angle of one is equal to the included angle of the other, the triangles are similar. 2021 © Learners' Planet, All rights reserved.

The hypotenuse is the longest side of the triangle. 3. Pythagoras Property: (i) In a right-angled triangle, the square on the hypotenuse = sum of the squares on the legs. ► In a triangle, if the square on one side is equal to the sum of the squares on the remaining two sides, the angle opposite to the first side is a right angle. Right triangle is the triangle with one interior angle equal to 90°. Perpendicular is the side that makes right angle with the base of the triangle. The right angle is made up of the two shorter side 6. In other words, the acute interior angles of a right triangle … In the figure above, the side opposite to the right angle, BC is called the hypotenuse. ► If two sides of a triangle are unequal, the longer side has greater angle opposite to it. ΔABC and ΔDEF are said to be similar, if their corresponding angles are equal and the corresponding sides are proportional. The exterior angle of a triangle is always equal to the sum of the interior opposite angles. The session will be conducted in Hindi and the notes will be in Hindi.
