This around the world (also known as a scavenger hunt) has 12 problems.  There are three types of problems.  The first is finding the perimeter of a polygon given the coordinates of the vertices.  The second if finding the area of a right triangle, square, or rectangle given the coordinates of the vertices.

Cevian Triangles - A cevian is a segment drawn from a vertex of a triangle to the opposite side. In this case the point on the opposite side is a trisection point. These cevians create seven triangles, and each triangle has an area that is a multiple of 1/21 of the area of the original triangle. Can you find the area of each region?

The centroid of a Triangle is the centre of the triangle, which is the point of intersection of all the three medians of a triangle. If we have an object, then we can say that the centroid of that object is its centre. The centroid of the triangle separates the median in the ratio 2:1. The centroid of a triangle can be got by finding the average of the x-coordinate’s value and the average of the y-coordinate’s value of all the vertices of the triangle.
