show whether the argument is valid or invalid by constructing a correct circle diagram
1. no one who has studied logic reasons fallaciously. all the philosophy professors at indiana state university have studied logic. so, none of the philosophy professors at indiana state university reason fallaciously.
2. some wars are positively brutal. but was is never necessary. so brutality is never necessary.

answer: ask

step-by-step explanation:

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.
