Why is it impossible for a triangle to contain an 180 degree angle?

The sum of the three included angles of a triangle always = 180 degrees. So if one angle = 180 degrees (a straight line) then the other two included angles will be = 0 degrees which cannot make a triangle.


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.


How do you find the nearest degree of a triangle?

You cannot. An angle of a triangle can have any value between 0 and 180 degrees.


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


What is a a triangle with a 90 degree angle?

A right angle triangle


Why cant you have two obtuse angles in a triangle?

Angle sum property of a triangle states that the sum of angles in any triangle should be 180 degree. An angle greater than 90 degree is an obtuse angle. If we have 2 obtuse angles in a triangle, say, 95 degree, 100 degree & 50, it always tend to violate the angle sum property of the triangle. So we cannot have 2 obtuse angles in a triangle.


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


Is scalene triangle cannot contain a right triangle?

A scalene triangle CAN also be a right triangle. For a triangle to be scalene, all 3 sides must be of different lengths. If you draw a triangle with a 90 degree right angle (ie. a right triangle) you will see that it's very easy for the sides to be unequal lenghts.


What is a triangle with one 90 degree angle?

A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.


What is a triangle with angle of 37 degree's and 75 degree's?

The third angle is 68 degrees which makes it a scalene triangle


What is the name of the triangle who haves a 90 degree angle?

A right angle triangle


What is the name of a 90 degree triangle?

A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
