The sum of interior angles of a triangle is always* 180°, so the following triangles are possible:
_____
The following are not possible triangles.
_____
* in plane Euclidean geometry. There are other topologies such that the sum of angles of a triangle differs from 180°.
Answer:
The number have to add up to 180 so
The measures of the interior angles of a triangle are 59°, 31°, and 90°.
The measures of the interior angles of a triangle are 90°, 40°, and 50°.
And
The measures of the interior angles of a triangle are 82°,38°, and 60°.
Are the answers
