Missing Side of Triangle Inequality Theorem

If the longest side of the triangle was 10. Then the two shorter sides must have a sum that is ....?

• any length

• equal to 10

• greater than 10

• less than 10

Will these three sides form a triangle?

• yes

• no

Given two sides of a triangle, the possible values for the 3rd side of the triangle must be ​ (a)   the difference of the two sides and ​ (b)   the sum.

• greater than

• smaller than

• equal to
