Is an isosceles triangle an obtuse?

Answer 1

It can be but need not be.

Answer 2

An isosceles triangle is also an obtuse triangle if one of its interior angles is greater than 90o, an acute triangle if all of its angles are less than 90o, and a right triangle if one of its angles is 90o.
Sure it can

Answer 3

Not always, but it can be. Isosceles triangles have two equal sides and therefore two equal angles. An obtuse triangle has one angle exceeding 90º.

Answer 4

all of the angles put together must equal 180 degrees. an equlatrial triangle has all 60 degrees angles. It depends on the top angle. TBH - i have no idea(:

Answer 5

yes
