Once similarity is established, the real fun begins: using proportions to find unknown lengths. The principle is simple: ...

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 ...

An understanding of how to use Pythagoras’ theorem to find missing sides in a right-angled triangle is essential for applying the theorem in different contexts. (3,1) is the coordinate that is 3 along ...
