QuestionTriangle $D E F$ is formed by connecting the midpoints of the side of triangle $A B C$. The lengths of the sides of triangle $A B C$ are shown. Find the perimeter of triangle $D E F$. Figures not necessarily drawn to scale.

Studdy Solution
Simplify the expression for the perimeter:
$$\text{Perimeter of } D E F = \frac{a + b + c}{2}$$
This shows that the perimeter of triangle $D E F$ is half the perimeter of triangle $A B C$.
The perimeter of triangle $D E F$ is half the perimeter of triangle $A B C$. If the perimeter of triangle $A B C$ is known, divide it by 2 to find the perimeter of triangle $D E F$.
