(7,8,9) AA test of similarity of triangle SAS test of similarity of triangle SSS test of similarity of triangle Basic Practice Set 1.3 – Similarity This set is based on the concepts of similar triangles and properties of similarity. Key Points Covered in this Practice Set: Definition of Similarity – Two figures are similar if their shapes are the same, though sizes may be different. For triangles: If their corresponding angles are equal and sides are in proportion. Conditions of Similarity in Triangles: AA (Angle–Angle): If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar. SSS (Side–Side–Side): If the corresponding sides of two triangles are in proportion, then the triangles are similar. SAS (Side–Angle–Side): If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in proportion, then the triangles are similar. Properties Used: Corresponding sides of similar triangles are proportional. Corresponding angles of similar triangles are equal. Applications in problems like dividing a line, finding unknown sides, proving two triangles similar, etc. Type of Questions in Practice Set 1.3: Proving similarity between given triangles. Solving numerical problems using similarity theorems. Word problems involving heights and distances using similarity. Problems based on proportionality of sides. 👉 In short: Basic Practice Set 1.3 introduces you to using similarity theorems (AA, SSS, SAS) to prove triangles similar and solve simple problems based on proportionality of sides and equality of angles #mathstricks #similarity #class10maths #maharashtraboard #similarity #geometry #jr.tutor #rosekidstutor #AAAtest #SSStest
