The sum of the interior angles of a triangle on a plane is always 180 degrees.
An interior angle is any angle on the interior of the triangle.
two opposite interior angles.
It will have 3 interior angles of 60 degrees that add up to 180 degrees and it is an equilateral triangle.
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
The three interior angles of any triangle always add up to 180 degrees.
Each interior angle of an equilateral triangle measures 60 degrees
Exterior angle.
exterior angle theorem
An interior angle is any angle on the interior of the triangle.
The 3 interior angles of any triangle add up to 180 degrees
In any triangle exterior angle plus interior angles = 180 degrees
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
The shape is a triangle.
two opposite interior angles.
It will have 3 interior angles of 60 degrees that add up to 180 degrees and it is an equilateral triangle.
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
The three interior angles of any triangle always add up to 180 degrees.
