Question

In abc medians ad and be intersect in g. a line passing through g and parallel to bd intersects ac in k prove that ac = 6ek

Answer 1

Step-by-step explanation:

in triangle ABC, line t is drawn through vertex A in a such way that t ║line BC.

a. which pairs of ∠s are ≅

Answer 2

Step-by-step explanation:

According to question,

G is the centroid which divides the median in 2 : 1

∴AD=3units=9cm

1unit=93=3cm

∴GD=3cm

BE = 3 units = 6 cm

3 units = 6 cm

1 unit = 63

2 units = 63×2=4cm

∴BG=4cm

△BGD is a right angle triangle

BD2=BG2+GD2

BD2=(4)2+(3)2

BD2=16+9

BD=25−−√

BD=5cm
