Step 1: Draw a Right Angle. Begin by drawing a right angle. This establishes the basic structure of your right triangle. Step 2: Mark the Given Angle. Use a protractor to accurately measure and mark ...

Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...

The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it to ...
