Question

∆ABC is a right angled triangle in which c=90° name one altitude of ∆ABC​

Answer 1

triangle ABC have two altitudes because triangle ABC is right angled triangle

and angle C =90

So segAC and segBC are two altitudes of triangle ABC

when we take AC ac the base then BC is the altitude as AC perpendicular BC

and

when we take BC as the base then AC is the altitude as BC perpendicular AC
