If in ΔABC, D and E are points on sides AB and AC respectively such that DE || BC and AD = 3 cm, DB = 2 cm, then AE equals:

In triangle ABC if DE is parallel to BC then by the Basic Proportionality Theorem AD divided by DB is equal to AE divided by EC and this property helps in proving similarity of triangles or finding unknown lengths in ...
