Geometry can be done with only a ruler and (pair of) compass, it is visual. trigonometry uses algebra, sine, cosine...

I would normally have said geometry but just 2 hours ago I heard this exact question on The Weakest Link .

drummerboy75,
Not really misleading
See the question saying "deals with TRIANGLES"???
AND one of the options has the word "Tri" in it
That's how you get the answer
Also "metry" from Geometry merges with "Tri" which is short of word "Triangle"
That's how it is Trigonometry

Always good to use double chance for this type of question
