How do you do this? I am really confused.

B) both shapes have all angles of equal measure

Step-by-step explanation:

Squares and equilateral triangles have all angles of equivalent measure. Squares have 90 degrees on all 4 sides and equilateral triangles have 69 degrees on all 3 sides

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

multiply then divide
