Similar triangles can be used to find the height of objects.
Proportional Altitudes TheoremIf two triangles are similar, thencorresponding altitudes are proportional to a pair of corresponding sides.
Let’s think about why this theorem is true. Assume , why is ?
Proportional Medians Theorem If two triangles are similar, then corresponding medians are proportional to a pair of corresponding sides.
Proportional Angle Bisectors TheoremIf two triangles are similar, then corresponding angle bisectors are proportional to a pair of corresponding sides.
Proportional Segments TheoremAn angle bisector of a triangle divides the opposite side into segments which are proportional to the remaining two sides.
