a triangle can have only one right angle because the sum of all the three angles of a triangle has to be 180. so if there are more than one right angles, the sum of the angles will exceed 180 and hence the plane figure will no longer be a triangle
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
A triangle can have at most one right angle.
one
As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.
one.
One

A triangle can never have three right angles
3
None
i think it has 1 right angle
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)
None. If there was a right angle then it would not be called an acute triangle.
