Ple: Isabel builds two identical rectangular
doors for her puppet theater. There is
a square window in the top half of each
door and each bottom half is solid, as
shown in the diagram below.
30 in.
40 in.
In the diagram, d represents the length,
in inches, of the diagonal brace on the
bottom half of each door. What is the
length of each brace in inches?

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.
