The circumcentre of an obtuse-angled triangle lies—

ainside the triangle
boutside the triangle
con the longest side
dat the obtuse vertex

ব্যাখ্যা

An obtuse angle exceeds $90^{\circ}$ , which pushes the meeting point of the perpendicular bisectors beyond the triangle. Therefore the circumcentre of an obtuse-angled triangle lies outside it.
