Let us now discuss a very important theorem related to triangles known as the triangle proportionality theorem. Triangle Proportionality Theorem: If a line is drawn parallel to any one side of a triangle in such a way that it intersects the other two sides in two distinct points then the other two sides of the triangle is divided in the same ratio. Triangle Proportionality Theorem PROBLEM The Triangle Proportionality Theorem states: "If a line parallel to one side of a triangle tersects the other two sides, then it divides the two sides proportionally." Given: BC Il DE BD _ CE Prove: Write a paragraph proof to prove triangle ADE is similar to triangle ABC.

that includes proportionality of the sides as part of the deп¬Ѓnition of similar triangles, this theorem would be rephrased to say that if two triangles have congruent corresponding angles, then they are similar. Some textbooks, for some reason, do not prove this theorem at all, but instead take it вЂ¦ Triangle Proportionality Theorem If a line parallel to a side of a triangle intersects the other two sides, then it divides them proportionally. 5.

Basic Proportionality Theorem Proof. Let us now try to prove this the basic proportionality theorem statement. Consider a triangleО”ABC as shown in the given figure. In this triangle, we draw a line PQ parallel to the side BC of О”ABC and intersecting the sides AB and AD in P and Q respectively. According to the basic proportionality theorem as The intercept theorem, also known as Thales' theorem (not to be confused with another theorem with that name) 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.It is equivalent to the theorem about ratios in similar triangles.
