ABC is isosceles with AB=AC=8 units and BC=6 units. D and E are midpoints of AB and BC respectively. The length of AC IS 8 units. The length of DE IS ___. Units.

Answer:
DE = 4 units
Explanation:
The line segment DE is joining the midpoints of AB and BC. By the midpoint theorem:
Therefore:
[tex]\begin{gathered} DE=\frac{1}{2}AC \\ =\frac{1}{2}\times8 \\ =4\text{ units} \end{gathered}[/tex]The length of DE is 4 units.
