Two obtuse angles.
There are four types of concave (not cocave) hexagons:one reflex angle,two reflex angles, opposite one another,two reflex angles with one next-but-one to another,three reflex angles alternating.This site is not suitable for displaying images.

Please restate this question for clarification...
to protect our body from harmful stuff.
Simple reflex arcs, where a sensory neuron directly synapses with a motor neuron in the spinal cord, do not involve an association neuron. These reflex arcs allow for immediate and involuntary responses to stimuli without the need for processing in the brain. Examples include the knee-jerk reflex and withdrawal reflex.
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
Visceral reflex arcs involve involuntary responses in internal organs, modulated by the autonomic nervous system. In contrast, somatic reflex arcs involve voluntary responses in skeletal muscles, controlled by the somatic nervous system.
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
The patellar reflex, commonly known as the knee-jerk reflex, uses just two neurons. When the patellar tendon is tapped, a signal is sent along a sensory neuron to the spinal cord, which synapses with a motor neuron to trigger the contraction of the quadriceps muscle and extend the leg.

ANS reflex arcs are stimulated by input from sensory or visceral receptors. The signals are processed in the hypothalamus (or regions of the spinal cord) and target effector control is then regulated via myelinated preganglionic neurons
The two main types of dispersion halos are circular halo, which forms a ring around the sun or moon, and the parhelia or sundogs, which are bright spots seen at a 22-degree halo around the sun. Other less common types include tangent arcs, upper tangent arcs, circumzenithal arcs, and supralateral arcs.
A reflex action is an action that happens almost instantly without conscious thought. Grasp a very hot handle of a saucepan on the stove, and you immediately release the handle to avoid further burning by reflex action.
