1. 7-4: Proportions in Triangles Rigor: apply the side-splitter theorem and the triangle-angle-bisector theorem. Relevance: ground planning

2. Notes: The Side-Splitter Theorem Highlight this theorem in your core book on page 303. The book calls it the Triangle Proportionality Theorem, but it is better known as the side-splitter theorem. We will solve it on pg 303.

3. Example 1: What is KP?

4. Corollary to the side-splitter theorem

5. Example 2: Campsites What is the length of Site A along the river?

6. Triangle-Angle-Bisector Theorem If a ray bisects an angle of a triangle, then it divides the opposite side into 2 segments that are proportional to the other 2 sides.

7. Example 3: Solve for y.
