Hi friends, welcome to Maths Master, here you will learn how to solve Practice set 1.2 of Maths 2 Similarity is an easy and simple way.
Basic proportionality theorem
If a line parallel to a side of a triangle intersects the remaining sides in two distinct points, then the line divides the sides in the same proportion.
Converse of basic proportionality theorem
If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side.
Property of an angle bisector of a triangle
The bisector of an angle of a triangle divides the side opposite to the angle in the ratio of the remaining sides.
Property of three parallel lines and their transversals
The ratio of the intercepts made on a transversal by three parallel lines is equal to the ratio of the corresponding intercepts made on any other transversal by the same parallel lines.
