180 degree.
3Same answer with an explanation:In an equilateral triangle, all sides are the same length and all three interior angles have the same number of degrees (60 degrees each).

A straight angle has 180 degrees. A triangle is a polygon whose interior angles add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
The sum of the interior angles for any polygon can be found by the formula 180 degrees multiplied by n-2, where 'n' is the number of sides of a polygon. If the polygon is a triangle, then the sum of the interior angles is 180 degrees because n is equal to three, the number of sides in a triangle.
All triangles have 3 interior angles that add up to 180 degrees
None because a scalene triangle has three unequal sides.
The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides
Because the formula for finding the total sum of interior angles of any polygon is:- (number of sides-2)*180 = total sum of interior angles A triangle has 3 sides so: (3-2)*180 = 180 degrees
using the equation (A-2)180 Where A is the number of angles in a polygon with equivalent angles. (8-2)180 (6)180 1080 degrees total. 1080 / 8 = 135 degrees per angle. 1080 is the total degrees of all interior angles. 8 is the number of angles.
Because the formula for finding the total sum of interior angles for any polygon is: (number of sides-2)*180 = total sum of interior angles A triangle has three sides so: (3-2)*180 = 180 degrees
The sum of the interior angles of a polygon depends on the number of sides. The formula for n sides is sum = 180 (n-2) So for a triangle it is 180 degrees, for a quadrilateral 360 degrees, and for a pentagon 540 degrees.
