Trigonometric Functions and Triangles
... We give these two important laws and some of their applications without proof. These two laws are useful in solving oblique triangles, that is triangles with no right angles. We adopt the following convention. We label the angles of the triangles A; B; C, and the lengths of the corresponding opposit ...

Paper Folding And The Theorem of Pythagoras
... After step 8 you will have a boat. What is its shape? If you look closely you find creases which show many right angled triangles. Now unfold the boat. Remember we started with a plain square paper. Now look at the creases appearing in the unfolded boat. You will see a pattern which is known mathema ...
