Geometry Exercise - Line Segments and Angles

Adding two line segments means placing them end-to-end and forming a new segment whose length is the sum of the original two segments.

Subtracting line segment 'a' from line segment 'b' means finding a new segment whose length is the difference between 'b' and 'a'.

Doubling a line segment means creating a new segment with twice the length of the original segment. Adding another segment 'a' is then done by placing it adjacent to the doubled segment.

Tripling a line segment means creating a segment with three times the length of the original. Subtracting segment 'b' involves finding the remaining length after removing 'b' from the tripled segment.

Drawing an angle with a specific measure involves using a protractor to mark the desired angle and a ruler to draw the lines that form the angle.
