(Transversal)

What is transversal ?

It means to place across' so it means to basically cut something . We are learning the lines that cut paralleral lines are called transversal

Angles formed by transversal ?

• Interior angles- all angles that are inside the figure

• Exterior angles- all angles that are outside the figure

• alternative interior angles- the 'Z' alternative angles that's inside

• alternative exterior angles- the 'Z' alternative that are outside

• corresponding angles

• co-interior angles
