@ganeshie8 can you explain this one?

ganeshie8 (ganeshie8):

Fix ur eyes on Triangle 2

ganeshie8 (ganeshie8):

Now, see that triangle 3 can be reflected in line \(l\) to get to trinagle 2

OpenStudy (highschoolmom2010):

I don't understand what the line l is is that another line of reflection???

ganeshie8 (ganeshie8):

in the given pic, i see 2 lines, and 3 triangles how many do u see

ganeshie8 (ganeshie8):

yes, l and m are just lines of reflection

OpenStudy (highschoolmom2010):

nvm line m is for triange 1&2 line l is for triangle 2 & 3

ganeshie8 (ganeshie8):

perfect !

ganeshie8 (ganeshie8):

u can reflect triangle 1 in m, u can reflect triangle 3 in l both will get u to triangle 2

ganeshie8 (ganeshie8):
