Transverse dunes are long sand ridges that are oriented at right angles to the prevailing wind direction. They form when wind blows sand over a stationary object, like a plant or rock, causing the sand to accumulate into a ridge perpendicular to the wind direction.
A rectangular representation of Earth that shows accurate directions but distorts sizes and distances is called a Mercator projection map. This distortion occurs because it preserves angles and lines of constant direction, commonly used for navigation over large bodies of water.
Cracks in rocks at right angles to the surface are typically the result of tensile stresses acting on the rock. These stresses can be caused by factors such as cooling and contraction, unloading and expansion, or tectonic forces. As the rock experiences these stresses, cracks form perpendicular to the direction of the stress, resulting in fractures that are often at right angles to the surface.
Photons oscillate (vibrate) along an axis that is perpendicular to the direction of the photon's travel. Photons are responsible for all electromagnetic radiation, including visible light, invisible light (infrared and ultraviolet), X-rays, radio waves, and magnetic waves. . When all photons in a beam of light oscillate in same direction, that is called polarized light.
Biotite (black mica) and muscovite (white mica) are both minerals that have perfect basal cleavage--one direction. It cleaves into thin sheets. Feldspars (albite, oligoclase, andesine, labradorite, bytownite, anorthite) have good cleavage in two directions at nearly right angles, poor in a third direction.

A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
using protactor, we use to draw angles in anticlockwise direction and that angles are called positive quadrant angles. and angles in clockwise direction, these angles are called negative quadrant angles.
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
congruent angles are simply two angles that are identical in degrees although they may not necessarily be pointing the same direction
