**The figure below is made up of Triangle FHJ and Trapezium ABDE. Given that GB // FC and BJC is an isosceles triangle, find Angle GHB.****Solution **

Angle BCF ----- 106 deg *

Angle BCJ ----- (180 – 106) deg = 74 deg **

Angle BJC ----- 74 deg #

Angle GBH ---- 74 deg *

Angle GHB ----- Angle BGF – Angle GBF ##

= (156 – 74) deg = **82 degrees (Answer)**

* corresponding angles

** angles on a straight line

# base angles of isosceles triangle

## exterior angle
