It is not common practice due to the fact that if mirrors are placed at right angles someone else could be looking at your privates from another angle which could be uncomfortable to you or the other person. in other words for basic privacy reasons.
At angle of 30 two mirrors will give nine reflected images.
They are ued all over the place for Ex. TV, oven, shelves, pizza, windows, mirrors, shoeboxes, and amything else like that.
Some shapes have angles and so they are important in defining the shapes. And angles are absolutely critical for angles. They are the very essence of their existence: if it were not for angles then there would be no angles.
Yes, congruent angles are angles that have the same measure.
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.
it goes in 3 separate angles
At angle of 30 two mirrors will give nine reflected images.
Glass is one such as mirrors. For example if you lined up mirrors at certain angles the light would bounce off onto the next mirror.
The mirrors are fitted at 45 degree angles in a periscope in the opposite directions. when you see through the periscope, the image gets reflected.
Shine a laser pointer onto mirrors set up at various angles.
With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
A periscope works using two mirrors placed at 45 degree angles and in the direction you wish to see. A periscope uses the two mirrors to bounce light from one place to another. The light comes through the lense, bounces off one mirror to the other and then into the person's eye.
If the angles of the mirrors that you used on periscope are not parallel to each other you would see the image upside down.
Those angles are equal at the point where a ray of light hits the mirror,regardless of the shape of the mirror.
You are seeing a reflection and you are seeing a reflection of the reflection.

As we place two mirrors inclined with each other then many images are formed. If @ is the angle of inclination then number of images is got by the formula [360/@] - 1 Hence as we place the two mirrors at right angles ie 90 degree then number of images will be 3 If both mirrors kept parallel facing each other then infinite images are formed.
