If a right angle triangle has an interior angle of 30 degrees then the other two angles must be 90 degrees and 60 degrees.
Not possible because all triangles have a total sum of 180 degrees interior angles.
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
All triangles have interior angles that add up to be 180 degrees
Interior angle is 150 degrees.
90 degrees
2160 total interior degrees.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees:- Right angle triangle has a 90 degree angle and 2 acute angles Scalene triangle has 3 different acute angles Obtuse triangle has 1 obtuse angle and 2 different acute angles Isosceles triangle has 2 equal angles and a 3rd angle that all add up to 180 degrees Equilateral triangle has 3 equal 60 degree angles
Providing it is a regular nonagon: Exterior angle: 40 degrees Interior angle: 140 degrees
180 - 36 = 144 degrees.
Triangles are always 180º when the angles are added up. There is no inside angle verses and outside angle.
If each interior angle is 165 degree then it's a regular polygon with 24 sides
