1 answer:
We know that
the lengths of any two sides of a triangle must add up to more than the length of the third side. (<span>Triangle Inequality Theorem)
Part a) </span><span>Could the third side of the reflective sticker be 6 cm long? Explain your reasoning. If this third side is possible,
we know that
3+4 > 6-------> 7 > 6-----> is ok
3+6 > 4------> 9 > 4-----> is ok
4+6 > 3-----> 10 > 3-----> is ok
</span>see <span>the attached figure
the answer Part a) is
</span><span>the third side of the triangle can be 6 cm
</span>
Part b) Could the third side of the reflective sticker be 1 cm long? Explain your reasoning
3+4 > 1-------> 7 > 1-----> is not ok
it can't be a triangle
the answer Part b) is
the third side of the triangle can't be 1 cm
