change of position, shape, or size of figure
That figure is best described as a "triangle".
Two rules associated with significant figure :-. When rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure. Then 0.000 must be kept to show the position of the decimal point. 763 are thus the three significant figures and no change is required as the first figure to be discarded is 2 and this is less than 5. The answer to 3 significant figures is 0.000763

No. However, the way in which it is described - in particular, what constitutes its base - may change.
You can show the change in position of a figure by using directional words such as up, down, left, right, forward, and backward. Additionally, you can use distance measurements or grid coordinates to describe the movement accurately. Diagrams or animations can also help to visually demonstrate the change in position effectively.
