Isosceles triangles equal 180 degrees

Answer 1

The total sum of angles of a triangle is 180, so only one angle of a triangle can be 90 ( making it a right angled triangle).

However the sum of two angles of a triangle can be equal to 90, once again making it a right angled triangle.

it is possible that two angle can be equal to 180-

The acute angles of a right triangle are complementary.

SUPPOSE ABC IS A TRIANGLE, where C = 90, thenA+B+90 = 180,A+B = 180-90or A+B = 90,or A = 90-B

so it's possible.

Answer 2

No, isosceles triangles do not have a fixed angle sum. The angles of an isosceles triangle can vary depending on the specific measurements of the triangle. However, any triangle, including an isosceles triangle, will always have angle measures that add up to 180 degrees.

Answer 3

The sum of the interior angles in every 2-d triangle is 180 degrees.

Answer 4

They can be, depending on the triangle.
