How does Geometry help architects?
It helps design buildings, measure dimensions, and create accurate plans.
What famous book written by Euclid became the foundation of Geometry?
Elements
What geometric figure is formed by two rays sharing a common endpoint?
Which tool is used to measure angles?

Why is a circle NOT considered a polygon?
Because it has curved sides and is not made of straight line segments.
