## If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct p...

Multiple choice question

If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio." This theorem is known as

## "If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the t...

Multiple choice question

"If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side." This theorem is known as converse of
