Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi5S5wpEbGdrcN5Y29ycA" class="cyc_term">BilaterallySymmetricObject</a> is a (tangible or intangible) spatial object that is symmetric with respect to some bisecting straight line (if the object is planar) or plane (if it's non-planar). In this context, <i>symmetric</i> means that the line or plane divides the object into two equal halves with the same shape (or mirror-image shapes). For example, a <a href="http://sw.opencyc.org/concept/Mx4rmSmWUM7yEdmAAAACs0uFOQ" class="cyc_term">Circle</a>, an isosceles <a href="http://sw.opencyc.org/concept/Mx4rvVjrapwpEbGdrcN5Y29ycA" class="cyc_term">Triangle</a>, a <a href="http://sw.opencyc.org/concept/Mx4rwQwzSJwpEbGdrcN5Y29ycA" class="cyc_term">Cone</a>, and a human body are all bilaterally symmetric objects. <p/> If a <a href="http://sw.opencyc.org/concept/Mx4rvVi5S5wpEbGdrcN5Y29ycA" class="cyc_term">BilaterallySymmetricObject</a> <code><b>OBJ</b></code> is a one- or two-dimensional planar region, then any bisecting line with respect to which <code><b>OBJ</b></code> is symmetric is an <i>axis of symmetry</i> (see <a href="http://sw.opencyc.org/concept/Mx4r4BM6CvVqEdmAAAACs0uFOQ" class="cyc_term">symmetricAxes</a>) of <code><b>OBJ</b></code>. If <code><b>OBJ</b></code> is a two- or three-dimensional non-planar object that is symmetric with respect to a bisecting plane <code><b>PLANE</b></code>, then any straight line with respect to which the space-region intersection of <code><b>OBJ</b></code> and <code><b>PLANE</b></code> is symmetric is itself an axis of symmetry of <code><b>OBJ</b></code>. Thus, a circle has an infinite number of axes of symmetry (viz. any straight line that intersects the circle and passes through its center); an isosceles triangle has exactly one axis of symmetry; a cone has at least one axis of symmetry; and a human body has no axis of symmetry (though it does have three <a href="http://sw.opencyc.org/concept/Mx4r-y7_GvfZEdmAAAACs0uFOQ" class="cyc_term">objectAxes</a> (q.v.)). <p/> See also <a href="http://sw.opencyc.org/concept/Mx4rvVkG_5wpEbGdrcN5Y29ycA" class="cyc_term">RadiallySymmetricObject</a>. animal by taxonomic phylum with samples biology topic AnimalByTaxonomicPhylumWithSamples-Biology-Topic A <a href="http://sw.opencyc.org/concept/Mx4rAmoSCGJbQdiSXZJvYiNhkQ" class="cyc_term">CycVocabularyTopic</a> and a <a href="http://sw.opencyc.org/concept/Mx4rtGXkHpNaEdqAAAACs0uFOQ" class="cyc_term">KBDependentCollection</a>.

SentientAnimal sentient animal clarifying collection type ClarifyingCollectionType A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>. Instances are collections that are usefully invoked for purposes of resolving ambiguity and confusion that arise from the use of non-perspicuous languages. Suppose a human or other intelligent agent uses a language, such as a natural language, that is rife with ambiguity, and uses a word WORD of that language whose intended reference is unclear: in the context WORD might refer to THING1 or to THING2, but not both. One strategy for resolving this ambiguity is to find properties of THING1 and THING2, say P1 and P2, that distinguish them from one another, and ask the speaker whether by &quot;WORD,&quot; s/he intended to refer to something with P1, or to something with P2. For example, the speaker might use the word &quot;bank,&quot; and in response one might ask whether a financial institution or a piece of shoreline was meant. Clearly, what values of P1 and P2 are chosen cannot be arbitrary; asking whether the speaker meant to refer to a multi-individual agent versus a non-agentive place is not as effective as asking the speaker to choose between the &quot;financial institution&quot; and &quot;shoreline&quot; interpretations described above. Instances of <a href="http://sw.opencyc.org/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a> just are those collections -- such as the collection of financial institutions -- that might plausibly be invoked to resolve cases of ambiguity of the kind described here. In particular, suppose TYPE1 is an instance of <a href="http://sw.opencyc.org/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a> and TYPE2 is not, and THING is an instance of both TYPE1 and TYPE2. The fact that (<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> TYPE1 <a href="http://sw.opencyc.org/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a>) is a reason to prefer TYPE1 over TYPE2 when calculating possible clarifying properties for THING.
