Ex 6.3, 1 (iv) 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 In β πππΏ and βπππ β π = β π =70Β° Also, ππ/ππ=2.5/5 = 25/(5 Γ10)=1/2 ππΏ/ππ =5/10=1/2 So, ππ/ππ=ππΏ/ππ =1/2 Hence, by SAS similarity criterion for two triangles β πππΏβΌβπππ Ex 6.3, 1(v) 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 In β π΄πΆπ΅ and β πΉπ·πΈ β A = β F = 80Β° π΄π΅/πΉπ·=2.5/5 = 25/(5 Γ10) =1/2 π΄πΆ/πΉπΈ=π΄πΆ/6 AC is not given So, π΄π΅/π·πΉ β π΄πΆ/πΈπΉ So , β π΄πΆπ΅ and β πΉπ·πΈ are not similar .
