None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
in plane geometry: all triangles have 3 angles which add up to 180 degrees, in a right triangle one of those 3 angles is 90 degrees.
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
No right triangle can have any obtuse angles inside it.
A triangle can have at most one right angle.
it depends on what type of triangle
one
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
3
Three.
As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.
Depends on the type of triangle. A right-angled triangle has ONE right angle - the remaining two angles total 90 degrees.
one.
