Question

Classify the triangle with angles measuring 120, 40, and 20.
A. Right
B. Acute
C. Obtuse
is it A?

Answer 1

What degree is a right angle?

Answer 2

90

Answer 3

Correct, and since there is no 90 degree angles you can remove that from the problem

Answer 4

its definitely c...obtuse triangles have one angle measuring more than 90 degrees

Answer 5

Since acute angles are less than 90 and there is a angle with 120 degrees
Obtuse is your best answer as it is more than 90 degrees

Answer 6

that's what I thought :) thanks guys

Answer 7

it is c
A right angle triangle would have to follow the rule
a^2 + b^2 = c^2
which it doesn't
its obtuse
