The sum of the three internal angles of a triangle is equal to 180 degrees. Since the two known angles are 50 degrees and 60 degrees, the third angle is equal to 180 - 50 - 60 = 70 degrees.
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Yes providing its 3 interior angles add up to 180 degrees
The 3 interior angles of any triangle add up to 180 degrees
A right angle triangle has a 90 degree angle with two acute angles and the 3 interior angles add up to 180 degrees
The sum of the interior angles of a triangle is 180 degrees. This is because one angle of a triangle is 60 degrees.
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
They are all 60 degrees.
The 3 interior angles of a triangle add up to 180 degrees
No because the 3 interior angles of a triangle must add up to 180 degrees and only a right angle triangle has 1 interior angle of 90 degrees.
Each of the interior angles of an equilateral triangle is 120 degrees.
The sum of the interior angles of a triangle on a plane is always 180 degrees.
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
