Please give me the definition of the word, "Subtends."  This is not in 
your on-line math dictionary.  

Thank you.

If you think of the side opposite say angle A in a triangle, then that 
side 'SUBTENDS' angle A.  The word is most commonly used for the chord 
of a circle, SUBTENDING an angle at the circumference or at the centre 
of the circle. You can also think of the arc of a circle subtending an 
angle at the centre or at the circumference.  The angle subtended is 
'opposite' the chord or arc.
