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 β π΄π΅πΆ and β πππ
β π΄= β P
β π΅= β Q
β πΆ= β R
β π΄π΅πΆ βΌ β πππ
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 β π·πΈπΉ
β π·+β πΈ+β πΉ = 180Β°
70Β°" "+80Β°" "+β πΉ" = " 180Β°
150Β° +β πΉ = 180Β°
β πΉ= 180Β° - 150Β°
β πΉ= 30Β°
In β π·πΈπΉ and β πππ
β πΈ=β π
β πΉ=β π
Therefore by AA similarity criterion for two triangles
β π·πΈπΉβΌ" " β πππ
