Because that is the definition of a latch.
A J-K flipflop is master-slave triggered because that is the definition of a J-K flipflop.
A D flipflop is edge triggered because that is the definition of a D flipflop.
a group of flip-flops sensitive to pulse duration is called latch whereas a group of flip-flops sensitive to pulse transition is called a register.
Flip flop is edge triggered device
flipflop is edge triggering and latch is level triggering
A latching circuit is a circuit with two stable states, which one can think of as 1 and 0, thereby being able to store one bit of information. In circuit diagrams, these are represented by cross-coupled NOR or NAND logic gates.

a group of flip-flops sensitive to pulse duration is called latch whereas a group of flip-flops sensitive to pulse transition is called a register.
A LATCH can be said as the another name of flip flop as the only difference between a latch and the flip flop is that a latch is an level triggered device where as flip flop is an edge triggered device .
Latch are 1 bit memory element. it will become flip flop if you use a clock control in latch latch is a level triggered device which is used to store the digital data only. and on the other ways for sequential circuit design we use flip flops.
flip flop:-> it work's on the basis of clock pulses.-> it is a edge trigerred , it mean that the output and the next state input changes when there is a change in clock pulse whether it may a +ve or -ve clock pulse.latch;-> it is based on enable function input-> it is a level trigerred , it mean that the output of present state and input of the next state depends on the level that is binary input 1 or 0.Both the flip-flop and latch are Sequential circuits....Flip flops are edge-triggered devices whereas latches are level triggered devices.latch does not have clock signal whereas flip flop does.Flip flop has two values while latch has only one value.A: A flip-flop can be set reset and pass date with a clock a latch is a two state switch of or onA flip flop will follow a clock a latch will remain status quo until it is unlatch. basically one does not use flip flop for latches and viceversa. both can be flip and latched by signals.
A D latch is level triggered. It will follow the input as long as the gate is true. Once the gate goes false, the output will stay at the last known value. A D flip flop is edge triggered. The output will not change until the edge of the gate. At that point, the output will go to the state of input, and then it will stay at that value.
Flip flop is edge triggered device
If the shift register is synchronized (uses clock) the control signal is level triggered. If the shift register is asycronized (no clock) the control signal is edge triggered.
Latch A latch remembers the last state it was told to with another latchingsignal Buffer A buffer merely strengthens a signal so that it canbe fanned out with integrity or drive a heftier device. Any amplifieris a buffer. It outputs a state only as long as the state persistson its input(s).
in level trigger mode, the input signal is sampled when the clock signal is either high or low whereas in edge trigger mode the input signal is sampled at rising or at the falling edge. lever triggering is sensitive to glitches whereas edge trigger is non sensitive.. example: latch for level trigger and flip-flop for edge trigger
flipflop is edge triggering and latch is level triggering
A transparent latch (or simply a latch) is a digital logic device that can store two stable states with a level sensitive control signal called enable/latch, when this control signal is in the enable state the latch device transparently passes its input signal to its output, when this control signal is in the latch state the latch device holds its output in the current state and ignores the input signal. This behavior is different from flip flops (e.g. D flip flop), which are usually clocked and often edge sensitive not level sensitive.
in the case of edge trigger, it may generate unwanted interrupt when input signal has glitch and so on. on the other hand if edge trigger not seen in some special situation (eg. when process in the service routin) level trigger preffered!
