Constructions (accurate drawings) can be made using a ruler, a pair of compasses and a pencil. A line which cuts an angle into two equal side angles is called an angle bisector. In geometry a ...

It is important to remember other angles rules, such as angles on a straight line add up to 180°, and to recognise angles in parallel lines. Make sure you are confident in applying Pythagoras’ theorem ...

Line-to-ground clearances dictate maximum line-loading levels, usually post-contingency, in many operating situations. Since measuring them all is not possible in real time, utilities must rely on ...

This structure is a good example of a running angle with a bridge crossing were structure deflections could impact clearance. Self-supporting steel monopoles with concrete drilled-shaft foundations ...
