How do you work out angles of a triangle if the angle on a straight line add up to more than 180?

You cannot do that easily. If the angles on a straight line add up to more than 180 degrees, you are not dealing with a Euclidean plane but with a convex surface. The angles of a triangle will depend on the curvature of the surface over the area covered by the triangle and this need not be constant.

Why is a straight angle not considered an angle in geometry?
A straight angle is an angle.
An angle that is adjacentand supplement to one of the interior angles of a triangle?
In a triangle, if an angle is adjacent (shares a side) and supplementary (adds up to 180 degrees) to one of the interior angles, it means that the two angles together form a straight line. In other words, the three angles of the triangle add up to 180 degrees.
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.
Does a triangle and a line have equal 180?
If you took the three angles of a triangle and glued them on a piece of paper side by side the outer sides would make a straight line. A triangles three angles add up equal 180 degrees. A straight angle,line, equals 180 degrees.
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.
What is the angle bisector of a triangle?
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
What does an angle on a straight line add up to?
A straight line adds up to 180. Just like the angles of a triangle
How is constructing a perpendicular bisector different to constructing an angle bisector?
A perpendicular bisector is a straight line that divides a side of a triangle in two and is at right angles to that side. An angle bisector is a straight line that divides an angle of a triangle in two.
Why is it impossible for a triangle to contain a 180 angle?
It is impossible to have a 180 degree angle because all three of a triangle's angles have to equal 180. If you have one angle of 180, then you would have 2 angles of 0, making a plain old straight line.
Why is a straight angle not considered an angle in geometry?
A straight angle is an angle.
An angle that is adjacentand supplement to one of the interior angles of a triangle?
In a triangle, if an angle is adjacent (shares a side) and supplementary (adds up to 180 degrees) to one of the interior angles, it means that the two angles together form a straight line. In other words, the three angles of the triangle add up to 180 degrees.
What is Angle sum property?
The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle
Does a triangle and a line have equal 180?
If you took the three angles of a triangle and glued them on a piece of paper side by side the outer sides would make a straight line. A triangles three angles add up equal 180 degrees. A straight angle,line, equals 180 degrees.
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.
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.
What proves that the angles of a triangle add up to be 180?
The 3 vertices of a triangle when cut off will tessellate to form a straight line and angles on a straight line add up to 180 degrees or simply use a protractor to measure each angle.
How many right angles are needed to form a straight angle?
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
