1. The Side Angle Side (SAS) similarity theorem states that:

If two sides of a triangle are proportional to 2 sides of another triangle, and the angles around each of these 2 pairs f sides are equal (congruent), then the triangles are similar.

2. That is, we notice the equivalent ratios:

 \frac{40}{20}= \frac{20}{10}

so \frac{EF}{FG}= \frac{HI}{IJ}

then if m(I)=m(F)=60°, the triangles EFG and HIJ are similar, by SAS similarity theorem.
