Oooohhhhhhhhh Oooommmgggg Brooooo
Their intersection is 7 because is you look at the coordinates of both A and B they have 7 in common
SAS similarity. the angle degree is the same. if you multiply 14 and 8 by a factor of 7 you get 98 and 56 which means the triangle have the same ratio making them similar. because of this ratio it makes the side similar therefore being a SAS similarity because the angle is between the sides.
