# Triangle Height Practice

To change the shape of the triangle, move points A, B, and C.
To determine the height, move the solid perpendicular line to pass through the vertex opposite the base.
Hide/Show the ruler by pressing the ruler button.
Change the base by pressing the corresponding base button.
Once the height is determined, the perpendicular line will no longer move. You must change the base to another base, and back again.
