Textbook Problem

Given: In     Δ A B C   ~ Δ D E F (notshown) (not shown) ∠ B ≅ ∠ F       and       ∠ C = ∠ E A C = 9 , D E = 3 , D F = 2 , F E = 4 Find: A B , B C

To determine

To find:

The value of AB and BC.

Explanation

Given:

In ΔABC and ΔDEF

BF and CEAC=9,DE=3,DF=2,FE=4

Calculation:

Draw sample diagram of ΔABC, ΔDEF

By Angle-Angle rule,

ΔABC similar to ΔDEF

Then,

Since, ΔABC similar to ΔDEF

ABDF
