Geometry 6-4 Parallel lines and Proportional Parts A. Proportional Parts of Triangles 1. Theorem 6-4 Triangle Proportionality Theorem If a line is parallel to one side of a triangle and intersects the other sides in two distinct points, then it separates these sides into segments of proportiona...
Corresponding Special Segments of Similar Triangles Lesson Summary Frequently Asked Questions What is an example of corresponding angles? Corresponding angles in similar triangles are angles that have the same measurement. One triangle may be much larger than another, but the triangles are similar if ...

The geometric Mean theorem describes the relationship between the length of the altitude on the Hypotenuse in a Right-angled Triangle and two line segments it forms on the Hypotenuse. It states that the geometric Mean of two segments is equivalent to altitude. With this theorem, you will be ab...
7.4: Parallel Lines and Proportional Parts p. 362-369 Th. 7-5: Proving Parallel lines with overlapping triangles If a line intersects 2 sides of a triangle and separates the sides into corresponding segments of proportional lengths, then the line is parallel to the 3rd side. ...
