Answer:
sometimes
Step-by-step explanation:
always and never would not make sense since saying it is possible that it is true or false.
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
It is always isosceles because it can be proved as follows:
The perpendicular bisector dissects the triangle into two, and it is the common side. Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.
