The unknown side lengths are
Large triangle 10
Medium triangle 2
Small triangle 12/5 or 2.4
Step-by-step explanation:
EFD to ABC is 0.4 or 2/5
EFD to GHI is 0.24 or 6/25
ABC to GHI is 0.6 or 6/10
This is my work. Also 2/3 is a repeating decimal so it’s actually 0.6...
Too much work!!!!!!!!!!!!
6 units (or whatever you’re measuring in)
Each little square represents 1 unit.
