The correct missing proof are Δ UXY ~ Δ UST and subtraction property of equality.
Two triangles are said to be similar if their corresponding sides are equal and if the ratio of the sides are in equal ratios.
The proof is as follows :-
The given steps are;
1. Δ STU with ST || XY, 1. Given
2. ∠1 and ∠2 are corresponding angles, 2. Def of corresponding angles
3. ∠3 and ∠4 are corresponding angles, 3. Def of corresponding angles
4. ∠1 ≅ ∠2; ∠3 ≅ ∠4, 4. Corresponding angles theorem
5. Δ UXY ~ Δ UST 5. AA similarity theorem
6. SU/XU = TU/YU 6. Def of similar triangles
7. SU = SX + XU, TU = TY + YU, 7. Segment addition postulate
8. (SX + XU)/(XU) = (TY + YU)/(YU) 8. Substitution property
9. SX/XU + 1 = TY/YU+1 9. simplification
10. SX/XU = TY/YU 10. subtraction property of equality.
Hence, the correct missing proof are Δ UXY ~ Δ UST and subtraction property of equality.
