triangle proportionality theorem

Answer 5

parallel line theorem, there can also be a converse, which is just the reverse.

Question 6

altitudes

Answer 6

if 2 triangles are similar, the side L or R of the right angles are proportional to the L and R of the other triangle.

Question 7

angle bisectors

Answer 7

if 2 triangles are similar, then the L and R sides of the bisector are proportional to the L and R of the other triangle, and the bisectors are proportional.

Question 8

medians

Answer 8

if 2 triangles are similar and have 2 congruent sides that correspond, then the other sides are proportional on each triangle.

Question 9
