Abstract: Methods and apparatus are provided for controlling a mobile terminal including a touch screen supporting a multi-touch input. The method includes: determining a number of one or more points inputted as a first touch input on the touch screen; when the number is 3, determining the first touch input as a three-point input; determining a size of a largest internal angle of a triangle generated by connecting points of the three-point input on the touch screen; displaying one of a linear tool and a circular tool based on a size of the largest internal angle of the triangle; receiving a second touch input; generating a line corresponding to the second touch input by interworking with one of the linear tool and the circular tool; and displaying the generated line on the touch screen.
