Question

the adjoining figure, line l, m and n are parallel to each other and G is mid-point of CD.

Calculate

a) BG if AD is 12cm

b) CF if GE is 2 cm

c) ED if FD is 7 cm​

Answer 1

Answer:

Given that,

The straight line l, m and n are parallel to each other

G is the mid-point of CD

FD=4.4cm

To find : ED

In △CDF

E is the mid-point of FD and m∥l

⇒ED=
