Question

how many degrees must the angles of the shapes at a vertex in a tessellation sum up to?
a. 180°
b. 270°
c. 360°
d. 90°

Explanation:

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

Answer:

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