Question

So ABC and DEF are the same triangle, this question is asking me to write an equation between the relationships of DEF. How do I write that?

Answer 1

Step-by-step explanation

The first step is to draw a representation of the given parameters.

Since this is a right-angle triangle, the Pythagorean theorem applies. This can be seen below;

`\text{Longest Leg}^2=sum\text{ of the square of the short legs}`

We can then apply it to the sides of the triangle.

DF is the longest side. Therefore,

Answer

`DF^2=DE^2+EF^2`
