| A | B |
|---|
acute angle,  | angle greater than 0° and less than 90° |
angle,  | figure formed by two rays with a common endpoint called a vertex |
congruent,  | having the same size and shape |
obtuse angle,  | angle greater than 90° but less than 180° |
parallel lines,  | lines in a plane that do not intersect |
vertex,  | on an angle or polygon, the point where two sides intersect |
alternate exterior angles,  | pair of lines that lie on opposite sides of transversal, outside the other two lines |
alternate interior angles,  | pair of nonadjacent angles that lie on opposite sides of the transversal |
| alternate | every other or second, taking turns in a pattern |
| interior | inside, inner |
| exterior | outside, outer |
corresponding angles,  | angles on same side of transversal, same side of the other lines |
| corresponding | similar in character, form, function |
exterior angle,  | angle formed by one side of a polygon and the extension of an adjacent side |
interior angle,  | angle on the inner sides of two line cut by a transversal |
same-side interior angle,  | pair of angles on the same side of a transversal and between two lines intersected by transversal |
similar,  | same shape, not necessarily the same size |
transversal,  | line that intersects two or more lines |
| adjacent | next to or adjoining something |
polygon,  | closed plane figure formed by three or more line segments |
