Tree angles have the sizes:
69°, 93°, 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.
No.
True or false:
DE not a side in any of the triangles.
This is a fundamental property of triangles in flat (Euclidean) geometry. It's like a mathematical law that never changes - just like how a circle always has 360°!
Close isn't good enough! The sum must be exactly 180°. If it's 179° or 181°, those angles cannot form a triangle in regular geometry.
Yes! You can have one angle larger than 90° (called an obtuse triangle), but the sum of all three must still equal 180°.
You cannot draw a triangle with these angles! In this case, is impossible to construct as a triangle.
