Assuming the question refers to all interior angles of 60 degrees, then the answer is an equilateral triangle. If it is just one angle being 60 degrees, it can be any polygon you like.
To work out the sum of all the interior angles of a shape, we use the formula: 180(n-2) In this formula, n = the number of sides the polygon has. This formula only works out the sum of the interior angles, so to finish it off, we divide the answer by n. The number you get from that is equal to one interior angle of the particular polygon you put in the formula. To work out the exterior angles, you need to know that: Exterior angle + interior angle = 180 degrees. So to get the exterior angle, all we have to do is take the interior angle from 180 degrees. Triangle: 180(3-2) = 180 degrees 180/3 = 60 degrees 180 - 60 = 120 degrees Interior angle: 60 degrees Exterior angle: 120 degrees Square: 180(4-2) = 360 degrees 360/4 = 90 degrees 180 - 90 = 90 degrees Interior angle: 90 degrees Exterior angle: 90 degrees Pentagon: 180(5-2) = 540 degrees 540/5 = 108 degrees 180 - 108 = 72 degrees Interior angle: 108 degrees Exterior angle: 72 degrees You could do this for a long time and check every single polygon up to a 360 sided shape, but that would take ages. If you think about it logically, we already know that: Triangle: Int angle = 60 degrees Ext angle = 120 degrees Integers? YES Square: Int angle = 90 degrees Ext angle = 90 degrees Integers? YES Pentagon: Int angle = 108 degrees Ext angle = 72 degrees Integers? YES Do that for as many as you can, and you'll get a decent idea of which ones do and which ones don't. Just a hint: The more sides a polygon has, the less chance that there'll be an integer for it's interior and exterior angles.
The angle of incidence is equal to the angle of reflection when a wave bounces off a mirror. If the wave reflects at an angle of 65 degrees to the normal (the line perpendicular to the surface at the point of reflection), then the angle of incidence is also 65 degrees. Thus, both the angle of incidence and the angle of reflection are 65 degrees.
The angle of incidence is equal to the angle of reflection when a wave reflects off a mirror. Therefore, if the reflected wave bounces off at an angle of 65 degrees, the angle of incidence would also be 65 degrees.
15 degrees
The angle of incidence would be equal to the angle of reflection. Therefore, the angle of incidence would also be 65 degrees.

The angle of incidence is also 55 degrees because it is reflected
The angle of incidence would also be 47 degrees. According to the law of reflection, the angle of incidence is equal to the angle of reflection when a ray of light reflects off a surface.
An angle is basically a measure of how far off from 180 degrees something is.
1. Use a protractor. 2. If given the interior angle, use the linear pair postulate. (180-interior angle measure) 3. If given that the polygon is regular, divide 360 by the number of angles.
The incident angle to the Mirror will be 10 deG.
First off do X-2 then (X-2) x 180. There is your answer For example, 15-2 = 13 13 x 180 = 2340. so a 15 sided polygon has an angle sum of 2340.
