60°

8

hexagon

Step-by-step explanation:

a) An equilateral triangle has 3 sides and 3 angles equal.

The sum of angles in a triangle is 180 degrees.

let each angle = x

3 angles = 3(x)

3x = 180

x = 180/3

x = 60°

Hence, the measure of each angle in an equilateral triangle is 60°.

b) Considering the options, the highest is 8. Starting from a quadrilateral(4) to a polygon, we can fit certain numbers of triangles in one vertex.

8 numbers can fit together at one vertex (no space between the triangles)

c) When 6 triangles are fit together in one vertex, the outside shape:

The shape is an hexagon
