Tree angles have the sizes:
50°, 41°, and 81.
Is it possible that these angles are in a triangle?
Let's remember that the sum of angles in a triangle is equal to 180 degrees.
We'll add the three angles to see if their sum equals 180:
Therefore, these cannot be the values of angles in any triangle.
Impossible.
Is DE side in one of the triangles?
This is a fundamental property of triangles in flat geometry! It's proven mathematically and never changes - no exceptions allowed.
No! Triangle angle sums must be exactly 180°. Any other sum means the three angles cannot form a triangle, period.
Always double-check your addition: . If you get 172° (not 180°), the angles are definitely invalid for triangles.
In regular flat geometry, no. However, in advanced curved geometry (like on spheres), angle sums can differ - but that's beyond basic triangle rules!
Think: 'Triangle = 180'. The word 'triangle' has 8 letters, and 1-8-0 reminds you of the angle sum!
