- 3. UNLOCKING CONTENT VOCABULARY CONVEXPOLYGONS: A CONVEX POLYGON IS A POLYGON WHERE ALL INTERIOR ANGLES ARE LESS THAN 180 DEGREES, AND NO VERTICES POINT INWARD. IN OTHER WORDS, A LINE SEGMENT DRAWN BETWEEN ANY TWO POINTS IN THE POLYGON WILL ALWAYS LIE INSIDE OR ON THE BOUNDARY OF THE POLYGON.
- 4. UNLOCKING CONTENT VOCABULARY NON-CONVEX(CONCAVE) POLYGONS: A NON-CONVEX OR CONCAVE POLYGON IS A POLYGON THAT HAS AT LEAST ONE INTERIOR ANGLE GREATER THAN 180 DEGREES. THIS TYPE OF POLYGON HAS AT LEAST ONE VERTEX THAT POINTS INWARD, AND A LINE SEGMENT DRAWN BETWEEN SOME POINTS WITHIN THE POLYGON MAY PASS OUTSIDE IT.
