Question

Point E bisects side CD of parallelogram ABCD and CF intersects DA produced at G such that CF|AE, where F is a point on AB. The value of AD x GF - CF x AG is​

Answer 1

Answer:

In △ABE and △CFB,

∠ABE=∠CFB (Alternate angles)

∠BAE=∠BCF (opposite angles of a parallelogram)

∴ By AA criterion of similarity, △ABE ∼ △CFB
