One (1) is the most.
A triangles angles must add up to 180 degrees, no more or less
There are 3 angles in a triangle and they add up to 180 degrees
Every triangle has three angles, regardless of what kind of triangle it is.
they add up to 180 degrees
a right triangle. lol
Yes
Every triangle has 3 interior angles that add up to 180 degrees.
no, because a triangle has to be180 degrees and since a right triagle has to have a 90 degree angle the other two angles can't be bigger than 90 degrees, which is the requirement in order to be an obtuse triangle.
The hypotenuse
Most quadrangles do not have right angles. A rhombus is one example.
Most of the time, rhombuses have no right angles, but a square is also a rhombus, so if it was a sqare, then there would be four right angles, but it will most likely be none.
Quadrilaterals have four sides, and therefore four angles, so the most right angles it could have is four, like a square.
