 Hello and welcome to the session. I am Alka. Let's discuss the question. Say which pair of triangles in figure 6.34 are similar? Write the similarity criteria used by you for answering the question and also write the pair of similar triangles in the symbolic form. Given figures are LMP and DEF. Let's start with the solution in triangle LMP triangle F. We observe that LMP upon DE equal to equal to 1 upon 2. Similarly LP3 upon 6 equal to 1 upon 2 upon EF equal to 297 upon 5, 27 upon 50. We observe that LMP upon DE is equal to LP upon DF but it is not equal to LM upon EF. Therefore we can say that the ratio of the sides of these triangles are not equal so the two triangles are not similar. Therefore the ratio of sides of these triangles are not equal so these are not similar. Hope you understood the solution and enjoyed the session. Goodbye and take care.
