Let ABCD be a square. E and F be points on AC such that AE=EF=FC=AC3. Then tan(DEBF) equals:
Let ABCD be a square. E and F be points on AC such that AE = EF = FC =AC/3. Then tan (ÐEBF) equals :
ABCD is a trapezium with AB∥DC. E and F are points on non-parallel sides AD and BC respectively such that EF∥AB. Show that AEED=BFFC.
