1

Vertices are the corner points where sides join.

2

Edges are the straight line segments that form the boundary.

3

Convex polygons have no indentations; the line between any two interior points stays inside.

4

Concave polygons have at least one indentation with a reflex angle (>180°).

5

Diagonals connect non-consecutive vertices.

6

A triangle has three sides.

7

Exterior angles are outside, formed when a side is extended.

8

Regular polygons have equal sides and equal interior angles.

9

Concave polygons have indents or reflex interior angles.

10

Adjacent interior angles along a straight boundary can sum to 180° (supplementary) when they form a straight line.
