Steps of construction:
1. Take any suitable radius and as the centre, draw an arc which cuts a ray at point .2. With point as centre and the same radius, mark an arc and name it as . Again put your compass at and with the same radius, draw an arc which intersects the initial arc at .
3. Fix your compass at , draw an arc with a convenient radius. Repeat the process by putting the compasses at and let the two arcs intersect at . Join . .
4. Now, bisect the obtained angle between and . Mark it as . _____

Step 1: Let us draw any line segment with scale pencil.
Step 2: Now, with centre and with any radius, lets draw an arc with compass, so that it cuts the line segment at .
Step 3: Next with centre and with the same radius, lets draw an arc which cuts the previous arc at .
Step 4: Now, the points and are joined and extended. The angle is formed _____.

In the first square paper, the sides are folded about the corner point , in a way as shown in figure , so that the two folded parts overlaps each other perfectly.
When it is unfolded, the folds are marked as in figure .
It is found that,
Again if the side is folded about the point such that coincides with , it is unfolded
Then, _____
