What triangle has a length or 12 12 24?

Answer 1

A triangle can't have sides with lengths of 12, 12, and 24.

Well, maybe you might call it a 'degenerate' triangle', with angles of 0°, 0°, and 180°.

The two sides of 12 and 12 together are just exactly long enough to reach from one end

of the 24 to the other, so they flop down and lie right on top of it. When you look at this

'triangle', it looks like a single line with a length of 24.

Answer 2

These are not possible lengths for a triangle because 12+12 is not greater than 24.
