How do you find the slope of an altitude from vertex A in a given triangle?

• Use both vertex A and one other vertex of the triangle to calculate the slope.

• Find the slope of the side opposite A and take its opposite reciprocal.

• Use vertex A and the midpoint of the opposite side.

• Use the slope of the side opposite A and that is the altitude slope.
