Best Answer

No. If you start at the North Pole and go 3 kilometres south, then turn East and go 3 kilometres and finally go back up 3 kilometres North you have a triangle with 2 right angles (90)

No. The sum of the angles in ALL triangles is equal to 180 degrees. No triangle's angles equal 360.

All the Angles and sides on Triangles are always going to equal 180 Degrees

The sum of the 3 angles of a triangle will ALWAYS equal 180 degrees.

Because the 3 interior angles of any triangle add up to 180 degrees

all inner angles are equal to 180 degrees

Assuming the question was if an isosceles triangle have angles that add up to 180 degrees, then yes. All triangles have angles that add up to 180 degrees.

all inner angles are equal to 180 degrees

Yes the 3 interior angles of any triangle add up to 180 degrees

never In non-Euclidean geometry triangles can have angles that are more or less than 180 degrees.

The sum of the angles of a four sided shape is equal to 360 degrees. One way to prove this is to draw a diagonal line connecting two opposite vertices, resulting in two triangles. Since the sum of the angles of a triangle equal 180 degrees, and there are two resulting triangles, then the sum of the angles of two triangles (180 + 180) will equal 360 degrees.

All triangles have internal angles summing to 180 degrees. An equilateral triangle has three equal angles, each of which is 180/3 = 60 degrees.

All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.

Yes.
