FAQs on Construction of Triangle given Lengths of 3 Sides(SSS Criterion) Video Lecture - Mathematics for Grade 7

1. What is the SSS criterion for constructing a triangle?
Ans. The SSS criterion stands for "Side-Side-Side" criterion, which states that if the lengths of all three sides of a triangle are known, then we can construct a triangle using those side lengths.
2. Can any three lengths form a triangle using the SSS criterion?
Ans. No, not every combination of three lengths can form a triangle. The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If this condition is not met, then a triangle cannot be formed.
3. Are there any other criteria for constructing a triangle apart from SSS?
Ans. Yes, apart from the SSS criterion, there are two other criteria for constructing a triangle: the SAS criterion (Side-Angle-Side) and the ASA criterion (Angle-Side-Angle). These criteria involve a combination of side lengths and angles.
4. Is it possible to construct multiple triangles with the same set of side lengths?
Ans. No, if the lengths of all three sides of a triangle are known, then there can only be one unique triangle that can be constructed using those side lengths. The shape and size of the triangle may vary, but the side lengths will remain the same.
5. Can a triangle be constructed if one side length is greater than the sum of the other two side lengths?
Ans. No, a triangle cannot be constructed if one side length is greater than the sum of the other two side lengths. In order for a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side. If this condition is not met, then a triangle cannot be formed.
