Yes, sir.
Ah, I understand; but then we should have it; now, we have not got it.
All in good time. But if we had drawn it, could we not drop the perpendicular?
Certainly.
That is all I meant to say.
But you were saying drop——
No doubt we cannot drop a perpendicular in a triangle unless the triangle exists, since then there is neither vertex of a right angle, hypothenuse, nor any thing else; but when I say, drop a perpendicular, I always suppose a triangle; and as it is evident that the triangle may exist, I do not express the supposition, but understand it.
I comprehend this; but then we should drop the perpendicular only in this triangle, but you spoke as if we might drop it in all triangles.
I only took this triangle for an example; we can clearly do with all others what we can do with this one.
With all?
