A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
Each triangle has 180 degrees on the inside angles.
An octahedron has eight faces, each of which is an equilateral triangle. It does not have any right angles, as the angles in an equilateral triangle are each 60 degrees. Therefore, an octahedron has zero right angles.
three each of 60 degrees
An isosceles triangle can have 1 right angle providing that the other 2 angles each measure 45 degrees.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
three
Each triangle has 180 degrees on the inside angles.
3 interior angles and each of them measures 60 degrees
2 each.
three each of 60 degrees
There are 3 angles in a triangle
A triangle has 3 angles.
An isosceles triangle can have 1 right angle providing that the other 2 angles each measure 45 degrees.
Each of the 3 angles measures 60 degrees. There are 180 degrees in a triangle.
If each of its 3 angles are 60 degrees then it is an equilateral triangle If each of its 3 angles are different acute angles then it is a scalene triangle
An equilateral triangle has 3 equal angles each measuring 60°An equilateral triangle for example has 3 equal angles of 60 degrees that add up to 180 degrees.
