Question

Work out the length of EF

Answer 1

EF = 2 cm

Explanation:

HK = HG + GK

10 = 4 + GK

GK = 10 - 4

GK = 6 cm

or

KG = 6cm

`\triangle EGH \cong\triangle KGF... (given)`

`\because EG\cong KG.. (cpct)`

`\therefore EG = 6 cm`

`\because FG\cong HG.. (cpct)`

`\therefore FG = 4 cm`

EF = EG - FG (E-F-G)

EF = 6 - 4

EF = 2 cm

Answer 2
