parallax is the view from two different lines of sight used to find the distance to the stars. To find the distance you must first find the distance of the base of the triangle, or the length from one position on earth to the other. In the photos we took, this would be the distance from the 2 strips of tape we stood on when we took the picture. Next you determine the angle to the distant object from each end of  the baseline, or angle from the direction of you looking at the star to the baseline. In the photos we took this would be the angle from the direction of you looking at the paper star to the baseline. Lastly, calculate the distance to the distant object from the baseline, or the baseline to the star. In the photos we took this would be the distance from the paper star to the baseline. The place where the line from the distant object to the baseline and the baseline meet needs to have a right angle. Also, the longer the baseline, the more accurate the distance
