Question

Draw orthocentre of obtused angled triangle step by step​

Answer 1

Answer:

The construction starts by extending the chosen side of the triangle in both directions. This is done because, this being an obtuse triangle, the altitude will be outside the triangle, where it intersects the extended side PQ. After that, we draw the perpendicular from the opposite vertex to the line. This is identical to the construction A perpendicular to a line through an external point. Here the 'line' is one side of the triangle, and the 'external point' is the opposite vertex.
