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

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

Example 1: What is KP?

Corollary to the side-splitter theorem

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

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.  

Example 3: Solve for y.
