A triangle can have more than 1 RIGHT angle
-
It is a false statement.
That is, in Euclidean geometry, no triangle can have more than one right angle, so stating that one can is stating a falsehood.
Mind you, some mathematicians consider a straight line to be a circle of infinite radius so there may be some who consider it possible for a Euclidean triangle with two right angles to exist but as such a triangle to exist it would have to have a third side of zero length with a matching opposing angle of zero degrees. And that view of it can actually lead to useful results. But the other 99.99999999% of mathematicians would disagree strongly! So it is a falsehood.
As to the other Answerer's request for rephrasing your question, you could make it clearer if you state it as follows:
In Euclidean geometry, which of the following statements are true and which are false?
And offensively though his point may have been made, you probably would get more answers if you present it like the above. Since getting more answers may often be helpful, it might be something to consider!
