Question

If two angles of a triangle are acute then the third angle

Answer 1

acute angle or an obtuse angle

Explanation:

Case I:

If two angles are of 60 then the third angle will also be 60

which is an acute angle.

As 60+60+60 =180

Case II:

If two angles are of 30

then the third angle will be 120

which is an obtuse angle.

As 30+30+120 =180

∴ We can see, if two angles of a triangle are acute angles, then third angle will be acute angle or an obtuse angle.

Answer 2

Then third angle will be acute angle or an obtuse angle. It could also be right angle.
