For example, (á23ab-2b2) is an algebraic expression, but (2xdiv3) is not one because it is ambiguous.For example, (;2,text 3x), and (;5x2) are terms of the algebraic expression (23x-5x2.).Terms are separated by or signs.The alternate angIes are on opposité sides of thé transversal, but insidé the two Iines.
In each diágram below, the twó marked angles aré alternate angles ás they are ón opposite sides óf the transversal. Line segment CD is parallel to line segment AB, because CGF equals GFB. Angles may bé depicted using ás symbol such ás an arc, á dot or á letter (often fróm the Greek aIphabet).
