Special Right Triangles (Geometry Emphasis)

                     Lesson 1

 

                                                            Problem: Find the length AW when the Angle Q is 45 degrees.

  

                                                           

                                                            Solution   Angle Q is 45 degrees and we have to find the value of AW 

                                                            Step 1:                         

                           

                                                            Solution   We know that tan Q = AW / AQ => tan Q =   AW / 4

Step 2:                                                                                  

                            

                                                            Solution   tan 45 x 4 = AW => AW = 1 x 4 = 4 

                                                            Step 3:  

 

                                                            Solution     Answer is : 4

                                                            Step 4:                                                           

Complete
