Best Answer

The internal angles of a triangle always total 180 degrees

The 180 degrees must be shared between the three corners (verticies)

A right angle is 90 degrees so yes you can have one right angle in a triangle, but you do not have to have one.

Take away the 90 degrees you have already used in the right angle

180 - 90 = 90

the remaining 90 degree must be shared between the other two corners, so you cannot have more than one right angle in a triangle.

A right angle triangle

No, a triangle can have up to one right angle, but it doesn't have to be a right angle in order to be a triangle. A right triangle had one right angle. so, NO

A right angle triangle.

A triangle can have only one right angle (90o). Such a triangle is called a right triangle.

Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
