How is it impossible for a triangle to contain a 180 degree angle?
Because the 3 interior angles of a triangle must add up to 180 degrees and not 1 angle on its own
Which triangle cannot contain 90 degree angle?
Acute
What is the thirty degree sixty and degree right triangle theorem?
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
Why is impossible a triangle to contain a 180 grades degree angle?
By definition, a triangle must have three angles. It is also known that the interior angles of a triangle must total 180 degrees. If a triangle contained a single interior angle of 180 degrees, the other angles of the supposed triangle would both have to be zero, and the supposed triangle would be a straight line.
Is a 100 degree triangle acute obtuse or right?
If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
