right angles and straight angles
4 90 degree angles
right (90˚) and 180˚ angles
They are perpendicular lines that meet at right angles which is 90 degrees.
Right angles of 90 degrees
That sounds like the description of a transverse wave.
Electromagnetic wave.

transverse wave
A transverse wave is a wave that vibrates at right angles. This right angle wave goes in the direction of its propagation.
perpendicular wave.
Transverse
The fields are at right angles to each other and to the direction of the wave.
