Check the length of all the sides and measures of angles.

Visualize the triangle and think what other conditions its (the altitude) satisfies.

Take the median as x and then find the value of line segment in x and solve the equation.

Altitude is a perpendicular drawn to the opposite side.

Obtuse triangle has one angle as an obtuse angle.

Plot the mid-point of triangle and then join it with opposite vertex.

Median is the line which joins the midpoint of the side to the opposite vertex.
