Can you please elaborate. I am not convinced with the similarity and the area formula that has been used below
Hi!
So, st. 1 itself is not sufficient.
St. 2 PQ =5, PR =10 => we can make infinite number of triangles (see attached pic)
St 1 + st 2. If angle PQR = 120, PQ=5, PR=10, we can draw only
one triangle. Not sure? Try to draw another type
Therefore, we can find the area of the triangle. Please note that in DS questions we do not have to find the value of the area like in PS. We just have to know whether we
CAN find the area with the data provided. So, as we can draw only ONE triangle with given values we will be able to calculate the area.
Hope this helps!
