What is the correct way to classify a triangle with angles that measure 20°, 40°, and 120°?
update - got a 6/10 by what my knowledge was
BUT, the actual answers are
1 - isosceles
2 - equilateral
3 - obtuse
4 - acute
5 - right, scalene
6 - obtuse, isosceles
7 - 40 degrees
8 - 23 degrees
9 - 63 degrees
10 - 30 degrees
Triangles with an angle greater than 90º are called obtuse,
triangles with 3 different angles, thus 3 different sides, are called scalene.
Some triangles, such as yours, can be both obtuse and scalene,
but a triangle with angles of 120°, 30°, 30° would be obtuse but not scalene.
