The vertices of a triangle are (1, 1), (4, 3), and (3, 5). Find the area of the triangle. As part of your solution, use graph paper, plot and label the coordinates of the vertices, and draw the sides of the triangle.

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
