1 “Is it better to be feared or respected? And I say, is it too much to ask for both?”

2 7.5: Proportions in Triangles LT: I will use the Side- Splitter Thm. and the Triangle Bisector Thm.

3 Side-Splitter Theorem Theorem 7-4: Side-Splitter Theorem: If a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally.

4 Side-Splitter Theorem Find the value of x.

5 Corollary to Side-Splitter Theorem Corollary to Theorem 7-4: If three parallel lines intersect two transversals, then the segments intercepted on the transversals are proportional.

6 Application Given that the edges of the panels of the sails are parallel, find the values of the variables.

7 You wanna try one? Find the values of the variables in the following figure.

8 Triangle-Angle-Bisector Theorem 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.

9 Triangle-Angle-Bisector Theorem Find the value of x in the following figure.

10 “Don’t worry Wilson, I’ll do all the paddling. You just hang on!”
