“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.
