7. Point Stars located at the western side of the memorial recognized the sacrifice of America's WWII generation and the contribution of our allies. A field of 4,000 sculpted gold stars on the Freedom Wall commemorate the more than 400,000 Americans who gave their lives. During WWII, the gold star was the symbol of family sacrifice. 

8. Ray a figure of Liberation standing full length with head turned to left looking to the dawn of a new day, right foot resting on a war god’s helmet with the hilt of a broken sword in the right hand and the broken blade in the left hand

9. Acute Angle Under the southern and northern arches one finds these words encircling the medallion: “1941- 1945 Victory on Land Victory at Sea Victory in the Air”

10. Obtuse Angle A series of bas-relief sculpture panels created by sculptor Ray Kaskey is set into the balustrades of the north and south ceremonial entrance walls. The unifying theme of the panels is the transformation of America caused by the country’s total immersion in World War II.

11. Right Angle DESIGN COMPETITION During Stage I, approximately 400 preliminary design visions were reviewed by an Architect-Engineer (A-E) Evaluation Board. Entries were evaluated on their originality, appropriateness, feasibility, and compliance with project requirements. The board selected six design visions to compete in Stage II

12. Line(s) Stage II design concepts were judged by a Design Jury. Evaluation criteria in this stage included design concept, past performance, specialized experience and technical competence, professional qualifications, and capacity to accomplish the work in the required time.

13. Line Segment(s) Fifty-six granite pillars celebrate the unprecedented unity of the nation during WWII. Each state and territory from that period and the District of Columbia is represented by a pillar adorned with oak and wheat bronze wreaths and inscribed with its name; the pillars are arranged in the order of entry into the Union, alternating south to north across the plaza beginning adjacent to the Field of Gold Stars.

14. Intersecting Lines Bronze sculpted rope symbolizes the bonding of the nation.

15. Parallel Line/Segments This star is similar to the one used to represent mother’s who have sons in the war. The middle star was added upon the death of a son during World War II.

16. Perpendicular Line/Segments Two 43-foot pavilions serve as markers and entries on the north and south ends of the plaza. Bronze baldacchinos are an integral part of the pavilion design. Four bronze columns support four American eagles that hold a suspended victory laurel to memorialize the victory of the WWII generation.
