7.4-7.6

7.4

If two corresponding sides are proportional, then the triangles are similar.

If the corresponding angle is congruent and the sides are proportional the triangle is similar.

Nothing confused me about 7.4. It was quite easy.

7.5

If a line intersects triangles in the middle it divides them proportionally

If a line divides 2 sides of a triangle proportionally it is parallel to the third side

The segment dividing triangle is half as long as the third side

This was easy

7.6

Dilation-a transformation from the center affecting the scale factor.

I had a hard time discerning the scale factors but I think I’ve got the hang of it now.
