180 degrees !
Sometimes it is if its 3 interior angles are acute angles and add up to 180 degrees
There are no set values for the angles of an isosceles triange. However there will be two angles that are of equal value, and the sum of the angles will add to 180 degrees.
180 degrees
If you meen the three angles, all tirangles angles add to 180 degrees. But all of the angles must be different, that's what makes it an acute triange. So three.
In some non-Euclidean geometries the 3 angles of a triange will add up to less than 180 degrees. In other non-Euclidean geometries they will add up to more than 180 degrees.
Since an equilateral triangle is also equiangular, all the angles have to be congruent. Because all the angles must also add up to 180 degrees, each angle is 60 degrees.
two
An isosceles triangle has 2 or more congruent sides and angles. A scalene triangle has 3 completely different sides and angles.
A triange is an abstract mathematical concept and doesn't have a length.
To find the perimeter of a triangle add up all three sides.
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.
explementary angles add up to 360 degrees supplementary angles add up to 180 degrees complementary angles add up to 90 degrees
