Question

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 1

DE = 4 units

Explanation:

The line segment DE is joining the midpoints of AB and BC. By the midpoint theorem:

Therefore:

`\begin{gathered} DE=(1)/(2)AC \\ =(1)/(2)*8 \\ =4\text{ units} \end{gathered}`

The length of DE is 4 units.
