Ex 6.3,1 (i) 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 βˆ† 𝐴𝐡𝐢 and βˆ† 𝑃𝑄𝑅 ∠𝐴= ∠P ∠𝐡= ∠Q ∠𝐢= ∠R βˆ† 𝐴𝐡𝐢 ∼ βˆ† 𝑃𝑄𝑅 Ex 6.3, 1 (vi) 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 βˆ† 𝐷𝐸𝐹 ∠𝐷+∠𝐸+∠𝐹 = 180Β° 70Β°" "+80Β°" "+∠𝐹" = " 180Β° 150Β° +∠𝐹 = 180Β° ∠𝐹= 180Β° - 150Β° ∠𝐹= 30Β° In βˆ† 𝐷𝐸𝐹 and βˆ† 𝑃𝑄𝑅 ∠𝐸=βˆ π‘„ ∠𝐹=βˆ π‘… Therefore by AA similarity criterion for two triangles βˆ† 𝐷𝐸𝐹∼" " βˆ† 𝑃𝑄𝑅
