Question

which of the following is not a polygon by definition? a. hexagon b. circle c. square d. triangle why are squares and other regular polygons often used in cultural mosaic artworks? a. they are resistant to wear b. they can tell stories or highlight cultural significance through patterns c. they are easy to draw d. they are symmetrical what is the purpose of using the compass tool to mark arcs along a circles edge when constructing an equilateral triangle in geogebra? a. to find the center of the circle b. to mark perpendicular bisectors c. to measure the angles of the triangle d. to ensure all sides of the triangle are equal to the radius of the circle

Explanation:

1. A polygon is a closed - figure made up of straight line segments. A hexagon, square, and triangle are made of straight line segments, while a circle is a curved figure.
2. Regular polygons are often used in cultural mosaic artworks because their patterns can tell stories or highlight cultural significance.
3. When constructing an equilateral triangle in GeoGebra using a compass to mark arcs along a circle's edge, it ensures all sides of the triangle are equal to the radius of the circle.

Answer:

1. B. Circle
2. B. They can tell stories or highlight cultural significance through patterns
3. D. To ensure all sides of the triangle are equal to the radius of the circle
