False. A square consists of four right angles, each measuring 90 degrees, which means it cannot have any obtuse angles. An obtuse angle is defined as an angle greater than 90 degrees, so it is not possible for a square to contain such angles.
False. An angle of 167 degrees is actually an obtuse angle. Think of it like this: if you were to draw it out, it would be wider than a right angle but not quite a straight line. So, in the world of geometry, 167 degrees is definitely in the obtuse angle club.
True
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.

No
False
Yes but anything over 90 degrees is an obtuse angle
true
True and all 3 angles must add up to 180 degrees.
true
It is true
