1. In the right triangles shown, the measure of angle ABC is the same as the measure of angle EBD. What is the length of side BE?

Please help me! I'm confused on how to get the missing side.

BC = 4  (pythagorean theorem)

 

BD = 2/3 (4)    Similar triangles   

BE = 2/3 (5)    Similar triangles

I understand how the side BC is 4 but how did you get BD or BE? What work did you do, a proportion?

Rules of similar triangles....

2 is to 3    as bd is to bc

2/3 = bd/bc

2/3 bc = bd

2/3  4 = bd

 

Then you can use the same rules (or pythagorean theorem) to find BE
