Theorems Chapter 8 Flashcards
The ratio of the perimeters of two similar polygons equals the ratio of any two —— ——-
corresponding sides
(SSS~)
If the ratios of the measures of the corresponding sides are equal, the triangles are similar
(SAS~)
If the ratios of the measures of the corresponding sides are =,
and the included angles are congruent
the triangles are similar
Side Splitter
if a line is parallel to one side of a triangle and intersects the other two sides it divides those sides proportionally
Three parallel line theorem
if three or more parallel lines are intersected by two transversals, the lines divide the transversals proportionally
Angle Bisector Theorem
If a ray bisects an angle of a triangle, it divides the opposite side into segments that are proportional to its adjacent sides
