3
Proportions in Triangles Math 2 - Lesson 33 Mr. Lopez

4
Side-Splitter Theorem (Cool Name) The side-splitter theorem states that if a line parallel to one of its sides intersects the other two sides then it divides those sides proportionally. (Hmmmm!!) A B C DE If DE || CB then,

5
How do we use the side-splitter theorem Mr. Lopez? If AD = x, AE = 5, DC = 16 and EB = 10, solve for x. A B C DE

6
More With The Side-Splitter Theorem If 3 parallel lines intersect two transversals, then the segments intercepted on the transversals are proportional. (Interesting!) a b c d

7
Can we practice this concept Mr. Lopez? Solve for x and y 1624 20 y 12 x

8
Triangle-Angle Bisector Theorem If a ray bisects an angle of a triangle, then it divides the opposite side into two segments that are proportional to the other two sides of the triangle. A BC D If AC bisects A then

9
Please Mr. Lopez, lets try it! Solve for x A BC D x 85 6
