It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
180-120-35 = 25 degrees
There is no such triangle because the 3 interior angles of any triangle add up to 180 degrees.
Each exterior angle measures 120 degrees
Acute
360 degrees and the polygon is an equilateral triangle.
180-120-35 = 25 degrees
There is no such triangle because the 3 interior angles of any triangle add up to 180 degrees.
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
The shape is a triangle.
The third angle measures 18 degrees.
Each exterior angle measures 120 degrees
Acute
The sum of the exterior angles of a triangle is always 360 degrees. Therefore, each exterior angle of a triangle measures 120 degrees.
360 degrees and the polygon is an equilateral triangle.
Equilateral Triangle
The 3 interior angles of this equilateral triangle will add up to 180 degrees
180 degrees and it is an equilateral triangle
