To solve this task:

1. Draw an Isosceles Triangle: An isosceles triangle has two sides of equal length and one side of a different length. Make sure it is not equilateral (where all three sides are equal).

2. Show Its Line of Symmetry: Draw a vertical line down the triangle from the vertex (top point where the equal sides meet) to the midpoint of the base. This line represents the triangle's line of symmetry.

Would you like me to generate a diagram for this solution, or provide further details on isosceles triangles? Here are five related questions for deeper understanding:

1. What distinguishes an isosceles triangle from an equilateral triangle?
2. Can an obtuse triangle also be isosceles?
3. How can you calculate the base angles of an isosceles triangle?
4. How does symmetry relate to isosceles triangles?
5. What is the role of the altitude in identifying the line of symmetry?

Tip: Always identify the two equal sides of an isosceles triangle to locate its line of symmetry accurately.
