MAFS.912.G-SRT.2.4: Prove theorems about triangles. (Theorems include: Triangle Proportionality Theorem or Side Splitter Theorem – a line parallel to one side of a triangle divides the other two proportionally.)
MAFS.912.G-SRT.2.5: Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.

| Learning Targets and Learning Criteria |
|---|
- apply theorems, postulates, or definitions to prove theorems about triangles and proportional parts of parallel lines, including:
- Triangle Proportionality Theorem- A line parallel to one side of a triangle divides the other two proportionally.
- Converse of Proportionality Theorem- If a line divides two sides of a triangle proportionally, then it is parallel to the third side
- Triangle Midsegment Theorem (side splitter theorem as applied to triangle) – a midsegment of a triangle is parallel to one side of a triangle and its length is one-half the length of that side.
- use triangle similarity to solve problems
- use triangle similarity to prove relationships in geometric figures.
