Problem 3: Find the points on a circle of its octants with the circle centered at (5,5) and has a radius of 8 units. (with the aid of the table shows the result) Problem 4: Translate the triangle ABC has vertices [A(8,6),B(8,9),C(4,6)]+9 units in the x-direction and 4 in the y-direction. (with the aid of the graph, show the result) Problem 5: Determine the coordinate of the vertices of triangle ABC[A(8,7),B(3,7),C(4,3)] after a counterclockwise rotation of 180 around the origin. (with the aid of the graph, show the result)
