Isosceles Triangle Challenge

Use the limited GeoGebra toolbar here to construct a triangle that ALWAYS REMAINS ISOSCELES no matter where you drag its vertices.

Select the ANGLE Toolbar Image tool to find and display the measures of all 3 angles of this triangle. What do you notice? (Be sure to select the MOVE Toolbar Image tool again so you can keep dragging the triangle's vertices around.)
