How many images will be formed if two plane mirrors placed at angle 60 degree?
Every one told you that 5 images will be formed. That's the correct answer. I want to tell you some more facts about the images formed….if you are interested…
Sorry for rough diagram ( not to scale)
Image 3 and 4 are actually image of image 1 and 2 in the mirror 2 and 1 respectively.
Image 5 is the brightest of all the 5 images as it is formed by overlapping of images of image 3 and 4 in mirrors.
All these images along with the object lie on a circle with intersection point of mirror as it's center.
And most importantly.. if you place your object unsymmetrically, final images will not overlap and you will see 6 images instead of 5.

How many people use DuckDuckGo?
This is a common optics experiment we use at school workshops.
The answer is (360/θ)−1. Theta is the angle in degrees. For 60 degrees, the Number of images is 5.
You can make your very own setup at home to test it. It feels good.
I used thermocol and cardboard. I marked the angles using a protractor and cut the grooves based on angles (I used 30, 60, 90, 120 and parallel). You can test the results. It works brilliantly.
Note: Don't forget to count the partial images formed at the joint of the mirrors. It counts as ONE.
Here are some snaps of the setup I had mad

a) 30 degree because if mirror are parallel then it have infinite no of images then angle is 0° so the minimum angle maximum images formed
