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.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
It is impossible to have a triangle with 3 right angles. It is possible to draw a triangle with three right angles on the surface of a sphere: www.metacafe.com/watch/769025/270_degree_triangle_yes_3_right_angles
No, an equilateral triangle as three 60 degree angles.
All triangles have three angles.
If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle
As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.
Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.
All three interior angles of a spherical triangle may be right angles.
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
