A angle that sums up to 180 degress
By definition, all triangles have 3 sides.
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.
An obtuse triangle
Yes, all obtuse triangles are similar if they have the same angles. This is because similarity in triangles depends on the corresponding angles being equal. However, obtuse triangles can vary in size, so while they can be similar, not all obtuse triangles are similar unless their angles are exactly the same.
It's true that an obtuse triangle is never right because obtuse triangles are bigger than right triangles, which are 90 degrees. Obtuse Triangles are always bigger than Right triangles(90 degrees) , so It is true.
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
they are both angkes
Of course not! There are obtuse and acute triangles.
Triangles may be right triangles equilateral triangles acute or obtuse triangles
No not all obtuse triangular are similar. :)
The least number of obtuse triangles, if all possible triangles are drawn for n points in a plane, is zero. If all the n points lie in a straight line, no triangles are possible and so no obtuse triangles are able to be drawn; thus for any number n, there is a possibility that no obtuse triangles can be drawn, so the least possible number of obtuse triangles drawn is zero.
