 Hello and how are you all today? My name is Priyanka. The question says construct the following angles and verify by measuring them by a protector. So I need to draw an angle of 105 degrees. So let me start off with my steps. Now here I know that 105 degrees can be broken down into 90 degree that I know how to draw and adding 15 degree to it. So what I can do is I will be drawing an angle of 90 degrees and 120 degree and then drawing a thereby sector that will give me 105 degrees, right? So the first step is to draw a line segment. Let's take x, y then I need to construct angle x, y, t equal to 120 degree and angle x, y, s equal to 90 degree. Now let us draw a line segment x, y first. Now at x, y I will be drawing an angle of 90 degrees. This is a 90 degree angle that will be y, x let's say now the second thing what we need to draw is y, x, s equal to 120 degree. This is a very easy thing to do. What I need to do is now I need to join x with the second arc that I draw and this will give me an angle of 120 degrees. So this whole angle let me name it as s that will be y, x, s is equal to 120 degrees. Now 105 degree will be there between them so I need to draw an bisector of that will be x, n that will be the bisector of these two angles. Now this is the bisector x, n that we have drawn. Now this 90 degrees plus this 15 degree will give you what? It will give you exactly 105 degrees, right? So this angle that is 90 degree plus 15 degrees is give you 105 degree, 90 degree we have already knew how to draw. Then I have drawn an angle of 120 degree and then bisected 90 degree and 120 degree to obtain the remaining 15 degree. So this is my required construction of 105 degree angle. Let me write down the required steps further also. So the third step was to bisect by drawing bisector x, n. Then the required angle is y, x, n. y, x, n is the required angle of 105 degrees, right? So this completes my session hope you enjoy and have a good day.
