Question

1. Triangle ABC and triangle EFD are: *PLEASE HELP

Answer 1

Option (3)

Explanation:

From the figure attached,

`(BC)/(FD)=(AC)/(ED)`

`(3)/(1)= (3.9)/(1.3)`

`(3)/(1)= (3)/(1)`

Therefore, these corresponding sides are proportional (In the same ratio).

Angle between these sides are also equal. (Given in the picture)

Since, SAS rule of similarity states that, two triangles will be similar if their corresponding two sides are proportional and angle between these two sides are equal.

Option (3) will be the answer.
