An isosceles triangle has at least two sides of equal length, which means it also has two equal angles opposite those sides. The sum of the interior angles in any triangle is always 180 degrees. Therefore, if the two equal angles are each denoted as (x), the equation would be (2x + y = 180), where (y) is the third angle. Thus, the angles in an isosceles triangle can vary, but they will always sum to 180 degrees.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
A right angled scalene triangle
The sum of inner degrees of a triangle is 180 degrees.
A right-angle triangle
In total, a triangle has 180 degrees.
180 degrees in a triangle.
It has 180 degrees, but one angle of the triangle has to be 90 degrees
A right angles triangle, as one of the angles in the triangle is 90 degrees.
A right angled scalene triangle
A right-angle triangle
The sum of inner degrees of a triangle is 180 degrees.
An obtuse triangle
No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
In total, a triangle has 180 degrees.
There are 180 degrees in every triangle.
There are 180 degrees in a triangle. Next question?
45 degrees is an angle, not a triangle.A triangle containing an angle of 45 degrees can be any kind of triangle except an equilateral triangle.
