Question

1. how many degrees must the angles of the shapes at a vertex in a tessellation sum up to?

a. 360°
b. 180°
c. 270°
d. 90°

Explanation:

In a tessellation, the angles at a vertex must fit together without gaps or overlaps. A full - circle around a point is \(360^{\circ}\). So, the sum of the angles of the shapes at a vertex in a tessellation must be \(360^{\circ}\).

Answer:

A. \(360^{\circ}\)
