Solution

Name and Explanation: 2 Marks

Yes, there exists a unique triangle for a particular set of sides. This is because 2 triangles having the same set of sides will be exactly identical. You can realize this by drawing 2 triangles with same set of sides and then trying to superimpose one over the other. You will find that they are exactly identical.

If the two triangles have equal sides, then the two triangles are said to be Congruent as equal sides are one of the criteria for congruency of triangles.

Two triangular billboards are installed on a highway. Let the billboards be represented by $△$ ABC and $△$ DEF. The billboards are mechanically designed in such a way that the names of the vertices of $△$ DEF are cyclically interchanged every 1 minute, i.e. the triangles remain the same way, only the names of the vertices change. At 10 AM, for the first time the positions of the billboards are such that we can say $△$ ABC≅ $△$ DEF. After x minutes, the billboards will be in such a way, that $△$ ABC≅ $△$ DEF for the second time. Find x.
