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.
In an isosceles triangle, two of the interior angles have the same number of degrees. This is because an isosceles triangle has two sides of equal length, which means the two base angles (the angles opposite those equal sides) are congruent. The third angle, called the apex angle, can be different from the base angles unless the triangle is also equilateral.
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.
