The answer depends on the level of your knowledge.
Suppose the base is of length b
and the vertical angle is x degrees.
Draw the base, AC, and its perpendicular bisector.
Calculate h = b/[2*tan(x/2)]. That is the height of the triangle so mark this point, B, on the perpendicular bisector.
Draw AB and BC.
Done!
An isosceles triangle has 1 vertical line of symmetry
An isosceles triangle
The Isosceles triangle only has one possible line of symmetry; and that is through the vortex, AKA: The middle, in a vertical line.
Depends on the orientation of the triangle.
For a right cone, it is a hyperbola which becomes and isosceles triangle when the section passes through the apex.

Vertical.
An isosceles triangle
You have an isosceles triangle, and a circle that is drawn around it. You know the vertex angle of the isosceles triangle, and you know the radius of the circle. If you use a compass and draw the circle according to its radius, you can begin your construction. First, draw a bisecting cord vertically down the middle. This bisects the circle, and it will also bisect your isosceles triangle. At the top of this cord will be the vertex of your isosceles triangle. Now is the time to work with the angle of the vertex. Take the given angle and divide it in two. Then take that resulting angle and, using your protractor, mark the angle from the point at the top of the cord you drew. Then draw in a line segment from the "vertex point" and extend it until it intersects the circle. This new cord represents one side of the isosceles triangle you wished to construct. Repeat the process on the other side of the vertical line you bisected the circle with. Lastly, draw in a line segment between the points where the two sides of your triangle intersect the circle, and that will be the base of your isosceles triangle.

assuming its an isosceles triangle, then its 16 cm high
Yes but only if it's an equilateral or an isosceles triangle otherwise it's the vertical perpendicular height
It will look like a right angle triangle with a 90 degree angle and two 45 degree angles and will have one line of symmetry
There is only one line of symmetry in an isosceles triangle. If you draw this triangle with the "odd" side as the base and then bisect it with a vertical line, you will have that one line of symmetry. The triangle can be folded in half along this line because each side is a mirror of the other.
show that the bisector of the vertical angle of an isosceles triangle bisects the base
It is the triangle's perpendicular altitude
Depends on the orientation of the triangle.
