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 ...

Polygons
... Now draw a not regular polygon with the same number of sides as your regular shape. Draw in the triangles from one vertex. Is there the same number of triangles? Can you establish a relationship? How can you determine the total number of degrees in a polygon? If the shape is a regular polygon, how d ...

... Take a triangle where angle b is 60º and angle a is 30º If side B is 1unit long, then side C must be 2 units long, so that we know that for a triangle of this shape the ratio of side B to C is 1:2 There are ratios for every shape of triangle! C=2 ...

The phrase “same size and same shape” has intuitive meaning and helps to paint a mental picture, but is ...
