Chloe is learning about shapes in math class. She learned that triangles have three sides and nonagons have nine sides. Chloe decided to make a number pattern comparing the sides of multiple triangles and multiple nonagons. Her unfinished pattern is shown.
Complete both patterns, then finish the statement below by choosing the correct answer from each drop-down menu.
Ten nonagons will have a total of
sides. This number is
the number of sides of ten triangles.
Triangles: 3, 6, 9, 12, 15
Nonagons: 9, 18, 27, 36, 45
Complete patterns:
Triangles: 3, 6, 9, 12, 15, 18
Nonagons: 9, 18, 27, 36, 45, 54
Ten nonagons will have a total of 90 sides. This number is the number of sides of ten triangles.
