Explanation:

this is just a matter of a very simple definition :

an acute triangle has only angles that are smaller than 90°.

an obtuse triangle has one angle that is larger than 90°.

a right or right-angled triangle has one angle with exactly 90°.

keep in mind, the sum of all angles in a triangle is always 180°.

so, there cannot be 2 angles with 90° or more than 90°.

therefore,

A : acute

B : obtuse

C and D : right
