We cannot connect the 74ls138 straight with a seven segment display; for that we need a 7447(7 segment driver).
To connect a common anode 7-segment display, you would typically connect the common anode pin to a positive voltage source and the individual segment pins to current-limiting resistors connected to the microcontroller output pins. When you provide a LOW signal to a segment pin, it will turn on that segment.
If line BE is the bisector of segment AC and the length of segment AB is 7, then segment AC must be equal to 7 as well, since the bisector divides AC into two equal parts. Therefore, AC = 7.
Programmable Logic Devices (PLDs) can be used to create custom logic circuits, including those that drive 7-segment displays. A 7-segment decoder takes binary input and activates the appropriate segments of the display to represent decimal digits. By programming a PLD, you can implement the logic required for the decoder, allowing for flexible design and easy modifications. This connection enables the display of numerical values based on varying input conditions.

not what those guys said
There is no specific name.
With a straight-edge and a compass:Swing arcs from each end of the segment with the compass (without changing the settings)Connect the intersections of these arcs.The resultant is a perpendicular bisector of the segment.

If you mean that the line segment endpoints are (-4, 0) and (7, 0) then the midpoint is (1.5, 0)
no
Take a compass, extend it about 3/4 of the length of the segment. Then from one end of the segment, draw a 180 degree arc. From the other end draw another arc. Connect the points where the arcs intersect. Where the line intersects with the segment is the midpoint of the segment. That is how you bisect a segment to find the midpoint - geometrically.
Programmable Logic Devices (PLDs) can be programmed to implement various logic functions, including those required for driving a 7-segment decoder. A 7-segment decoder takes binary input and activates specific segments to display corresponding decimal digits. By configuring a PLD, you can create the necessary logic circuits that translate binary inputs into the appropriate outputs for the segments of the display. This programmable nature allows for flexibility in design and the ability to easily modify functionality as needed.
