Is it possible for a triangle to have two perpendicular sides?

Two sides perpendicular to each other, yes; no problem. It's called a right-angled triangle - best known achievement of Pythagoras - and they're used every day to plot coordinates and calculate distances. read more

Two sides perpendicular to each other, yes; no problem. It’s called a right-angled triangle - best known achievement of Pythagoras - and they’re used every day to plot coordinates and calculate distances. What you may be trying to picture, though, is a triangle, ABC with side AC and BC both perpendicular to AB, ie a triangle with two right angles. read more

yes it can have two perpendicular sides it becomes right triangle . you have two ways to draw it : 1. draw a Square and draw one of its diagonals then you have two triangle with two perpendicular sides. read more

A triangle cannot have two sides perpendicular to a third side. The sum of the three angles of a triangle is exactly 180 degrees. It must have three sides and three angles. Thus, it cannot have two angles whose sum comes to 180 degrees. In a right triangle, two sides are always perpendicular. read more
