Question

Can you draw a triangle with a right angle and an obtuse angle? Why or why not?

Answer 1

Respuesta:

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.
