Question

I need help answering the questions for person 2 on my group assignment

Answer 1

The equation for the relation of sides of triangle can be obtained by similar triangle property.

Consider triangle ABC and triangle DBE.

`\begin{gathered} \angle CAB=\angle EDA\text{ (Each angle is right angle)} \\ \angle CBA=\angle EBD\text{ (common angle)} \\ \Delta CBA\cong\Delta EBD\text{ (By AA similarity condition)} \end{gathered}`

Determine the ratio of corresponding sides of simillar triangle.

`(CB)/(EB)=(BA)/(BD)=(CA)/(ED)`

Thus similar triangle property is used to set up the equation.
