Yes
False
True and all 3 angles must add up to 180 degrees.
False
false
False
False
False, because a triangle can have only 1 obtuse angle
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.
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. A transverse wave causes its medium to move perpendicular to the direction the wave travels. This means that the particles of the medium move up and down or side to side as the wave passes through.
True
False because it can have 1 obtuse angle and 2 acute angles providing that all 3 angles add up to 180 degrees.
False. The denser the medium, the faster a transverse wave propagates. This is because denser mediums have a higher resistance to deformation, which allows the wave to travel more quickly through them.
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.
false, they vibrate parallel
just think for a second... what does a transverse wave look like and what does visible light waves look like? the same? yes. yes it is transverse not longitudinal.
True. In transverse waves, the particles of the medium move perpendicular to the direction in which the wave is traveling. This results in a side-to-side motion of the particles as the wave passes through the medium.
