How can you construct an isosceles triangle if only given the base and the vertical angle and the base angles can not be used for construction?
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!

What is the symmetry of isosceles triangle?
An isosceles triangle has 1 vertical line of symmetry
What type of triangle has only 1 line of symmetry which is vertical?
An isosceles triangle
How many lines of symmetry can be drawn through 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.
What is the number of lines of symmetry of isocelence triangle?
An isosceles triangle has one line of symmetry, which is the vertical line that runs from the apex (the vertex opposite the base) down to the midpoint of the base. This line divides the triangle into two mirror-image halves. Unlike an equilateral triangle, which has three lines of symmetry, an isosceles triangle only has this single line due to its two equal sides.
How many vertical lines does a triangle have?
Depends on the orientation of the triangle.

How would you construct an isosceles triangle if only given the vertex angle and the radius of the circumscribed circle?
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.

What is the vertical height of a triangle with an area of 48cm2 and a base length of 6cm?
assuming its an isosceles triangle, then its 16 cm high
Is the altitude of a triangle is a segment whose endpoints are a vertex of a triangle and the midpoints of the side opposite the vertex?
Yes but only if it's an equilateral or an isosceles triangle otherwise it's the vertical perpendicular height
What is the number of lines of symmetry of isocelence triangle?

This line divides the triangle into two mirror-image halves.

How does an isosceles right triangle with vertical axis looks like?
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
Triangle with 2 lines of symmetry?
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
How many lines of symmetry in an isoceles triangle?
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.
If the bisector of the vertical angle of the triangle bisects the base prove that the triangle is isosceles?
show that the bisector of the vertical angle of an isosceles triangle bisects the base
