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.
The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. To find the exterior angle, extend one side of the triangle and measure the angle formed outside the triangle. You can then calculate this angle by adding the measures of the two opposite interior angles. This theorem is useful in solving problems involving triangle geometry and angle relationships.
It will have 3 interior angles of 60 degrees that add up to 180 degrees and it is an equilateral triangle.
two opposite interior angles.
In an equilateral triangle, each interior angle measures 60 degrees. This is because the sum of the interior angles in any triangle is always 180 degrees, and since all three angles are equal in an equilateral triangle, you divide 180 by 3 to get 60 degrees for each angle.
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.
It will have 3 interior angles of 60 degrees that add up to 180 degrees and it is an equilateral triangle.
two opposite interior angles.
In an equilateral triangle, each interior angle measures 60 degrees. This is because the sum of the interior angles in any triangle is always 180 degrees, and since all three angles are equal in an equilateral triangle, you divide 180 by 3 to get 60 degrees for each angle.
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
