In ΔABC, AD is a median. If points E, F and G are midpoints of AD, AE and DE, respectively, then what will be the are ΔBFG ? |
$\frac{1}{2}$ (Area ΔABC) $\frac{1}{8}$ (Area ΔABC) $\frac{1}{4}$ (Area ΔABC) $\frac{1}{2}$ (Area ΔBGC) |
$\frac{1}{4}$ (Area ΔABC) |
As points E, F and G are midpoints of AD, AE and DE, respectively AE = FE = EG = GD So, They divide the triangle ABD in 4 equal parts. AD is median . So, Area of triangle ABD = \(\frac{1}{2}\) × Area of triangle ABC Area of triangle BFG = \(\frac{1}{2}\) × ( \(\frac{1}{2}\) × Area of triangle ABC ) [ ⇒ AF = FE = EG = GD ] Area of triangle BFG = \(\frac{1}{4}\) × Area of triangle ABC |
