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 πππΏ and βπππ β π = β π =70Β° Also, ππ/ππ=2.5/5 = 25/(5 Γ10)=1/2 ππΏ/ππ=5/10=1/2 So, ππ/ππ=ππΏ/ππ=1/2 Hence, by SAS similarity criterion for two triangles β πππΏβΌβπππ Ex 6.3, 1(v) State which pairs of triangles in figure are similar.
