Similar Triangles
Theorem 1.5.1
Proof: Parallel implies Similar
Now, we need to see that the lengths of
corresponding sides are proportional.
Now, looking at the same decomposition and changing
our point of view on which side is the “base” and which line is the
“height”, we’ll follow the text’s suggestion and find that
When you compare by division you find:
By a similar construction,
thus corresponding sides are proportional -- after
using some algebra:
Show that DE is proportional to BC:
