Variations in elements that make a triangle results in distinct triangles. Recognizing these variations helps in interpreting changes that are possible with in a triangle.

==== Concept #: [[Similar and congruent triangles]] ====
==== Concept #: [[Similar and congruent triangles]] ====
Two objects are similar if they have the same shape, but not necessarily the same size. This means that we can obtain one figure from the other through a process of expansion or contraction, possibly followed by translation, rotation or reflection. If the objects also have the same size, they are congruent. Two triangles are said to be congruent to one another only if their corresponding sides and angles are equal to one another

+The concept of Thales theorem has been introduced in similar triangles. If the given two triangles are similar to each other then,
+
+* Corresponding angles of both the triangles are equal
+* Corresponding sides of both the triangles are in proportion to each other
