Side-Splitter Theorem

Front

What is the Side-Splitter Theorem?

Back

The Side-Splitter Theorem states that if a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

If DE is parallel to BC in triangle ABC, and AD/DB = DE/BC, what does this imply?

Back

This implies that the segments AD and DB are proportional to the segments DE and BC.

Front

In triangle ABC, if AD = 3, DB = 2, and DE = 6, how do you find BC?

Back

Use the proportion: AD/DB = DE/BC. Substitute the values: 3/2 = 6/BC, then solve for BC.

What does it mean for two lines to be parallel in the context of triangles?

Back

Parallel lines in triangles create proportional segments on the other sides of the triangle.
