Identify the correct justification for each step, given that AC intersects BE , mAFE=40 and mCFD=50 . The figure shows two lines A C and B E. These lines intersect at point F. Ray F D separates angle E F C into two smaller angles. It is given that AC intersects BE . By the ________, AFE and BFC are vertical s. By the ________, AFEBFC . By the ________, mAFE=mBFC . It is given that mAFE=40 . So, mBFC=40 by the ________. By the ________, mBFD=mBFC+mCFD . It is given that mCFD=50 . So, mBFD=40+50 by the ________. Simplify to get mBFD=90 . Thus, BFD is a right by ________
