Question

So I fell behind in my last semester geometry class, so right now I’m working with Pythagorean Triples. Here’s the screenshot of the work I’m doing and I’m confused on what “DEF” is? I drew my vertices for “ABC” but then it starts talking about measurements etc.

Answer 1

First, we set the points on the graph ;

A = (1,6) , B= (1,1) and C= (5,1)

Join the points and you obtain the first triangle.

For the triangle DEF we know that sides AB= DE and EF= BC, so it is the same triangle but with different letters on the points. Make sure to have a 90° angle on E. ( the same as angle B on triangle 1 )
