I need help with perpendicular lines?

Question

How can i draw lines in a triangle that goes perpendicular from each vertex running perpendicular to the other side??

Answer 1

It is impossible. For a vertex to have perpindicular lines, the angle at that vertex is 90°. A triangle can only have 1 90° angle, because all angles have to add up to 180°.

If a triangle had 2 90° angles, then the third angle would have to be 0° which isn't possible.

So the answer is you cannot draw a triangle that has perpendicular lines at every vertex.
