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
Interior angles are angles on a triangle that add up to 180
The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.
There are 3 interior angles in a triangle and they add up to 180 degrees
No - the interior angles of a triangle add up to 180°.
The interior angles of a triangle all add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
All interior angles in any triangle add up to 180 degrees. A scalene triangle will have 3 different interior angles that add up to 180 degrees.
The 3 interior angles of any triangle always add up to 180 degrees
The 3 interior angles of any triangle always add up to 180 degrees
Yes if it's a triangle because the 3 interior angles of any triangle add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
