Step by Step Solution
Step 1
For triangle I, it has three sides of
unequal lengths. Hence, it is a
scalene triangle.
Step 2
As for triangle II, it is not a scalene
triangle. This is because two of its
sides have the same length (9.3cm).
Step 3
As for triangle III, all of its internal
angles are different. Therefore, it is
a scalene triangle.
Step 4
For triangle IV, its internal angles are
60° each. This means that all the sides
of the triangle have the same length.
Hence, this is not a scalene triangle.
Step 5
Clearly, only triangle I and III are
scalene triangles. Therefore, the answer is
A.
