Ch. 8-5 Proportions in Triangles

Learn the lesson By: Elena Soto


Side-Splitter Theorem

If lines are || to one side of a triangle and intersects of the two sides, it divides then those side even.

Corollary To Theorem

If there is 3 lines are || that intersect two transversals, then the segments intercepted on the transversals are proportional


Triangle-Angle-Bisector Theorem

Is a ray bisects of a angle of a triangle , then it divides the opposite side into two segments which are even to the other two side of the triangle.
