hey mate!!
Astronomers can measure a star's position once, and then again 6 months later and calculate the apparent change in position. The star's apparent motion is called stellar parallax. The distance d is measured in parsecs and the parallax angle p is measuredin arcseconds.
Hold the arm with the finger stretched. ...Measure the distance between your eyes with a ruler.Measure b with your angle-measuring tool.Make a drawing on scale and find from that the distance between your eyes and your finger.
thankyou
