Converse of the triangle proportionality theorem APEX :)
The definition of a circle is not part of the triangle (or tringle, even) proportionality theorem.
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
Given a triangle and a line, if the line passes through two sides of the triangle parallel to the third side, then it cuts the sides proportionally.l

The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
The converse of Pythagoras's theorem states :- "If the square of one side of a triangle is equal to the sum of square of other two sides then the triangle is a right angled triangle""
The Pythagorean Theorem allows the mathematician to determine the value of the hypotenuse. The converse of the Pythagorean Theorem manipulates the formula so that the mathematician can use the values to determine that if the triangle is a right triangle.

The Pythagorean Theorem states that in a right triangle with legs a and b and hypotenuse c, a2 + b2 = c2. The converse of the Pythagorean theorem states that, if in a triangle with sides a, b, c, a2 + b2 = c2 then the triangle is right and the angle opposite side c is a right angle.

Given a triangle and a line, if the line passes through two sides of the triangle parallel to the third side, then it cuts the sides proportionally.l
