Consider the following statements : 1. Let D be a point on the side BC of a triangle ABC: If area of triangle ABD = area of triangle ACD, then for all points O on AD, area of triangle ABO = area of triangle ACO. 2. If G is the point of concurrence of the medians of a triangle ABC, then area of triangle ABG = area of triangle BCO = area of triangle ACG. Which of the above statements is/are correct?

State true or false. (a) The altitude of an acute-angled triangle lies outside the triangle. (b) the orthocentre of an obtuse-angled triangle lies outside the triangle. (c) the orthocentre is the point of concurrency of three medians of a triangle. (d) The vertex containing the right angle is also the orthocentre of a right-angled triangle.
