Ex 6.3, 1 (ii) State which pairs of triangles in figure are similar. Write the similarity criterion used by you for answering the question and also write the pairs of similar triangles in the symbolic form Finding ratio of sides π΄π΅/ππ =2/4 = 1/2 π΄πΆ/ππ=3/6 = 1/2 π΅πΆ/π π=2.5/5 = 1/2 Hence, π΄π΅/ππ =π΄πΆ/ππ=π΅πΆ/π π=1/2 Therefore , using SSS similarly criterion So, β π΄π΅πΆ βΌ β ππ π Ex 6.3, 1(iii) State which pairs of triangles in figure are similar. Write the similarity criterion used by you for answering the question and also write the pairs of similar triangles in the symbolic form Finding ratio of sides ππ/πΈπ·=2/4 = 1/2 ππΏ/π·πΉ=3/6 = 1/2 πΏπ/πΉπΈ=2.7/5 Here, the ratio of corresponding sides of both the triangles is not same β΄ , Ξ LMP and βπΉπΈπ·are not similar .
