Question

fundamental theorem of proportionality

Answer 1

If a line parallel to one side of atriangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.



If D E ¯ ∥ B C ¯ , then A D D B = A E E C.

Answer 2

hi mate,

fundamental theorem of proportionality

The triangle proportionality theorem states that if you draw a line constructed parallel to one side of a triangle intersects the other two sides of the triangle and divides the remaining two sides proportionally.

The intercept theorem, also known as Thales' theorem or basic proportionality theorem, is an important theorem in elementary geometry about the ratios of various line segments that are created if two intersecting lines are intercepted by a pair of parallels.
