PROBLEM TO BE SOLVED: To provide a step leading to a solution to questions of geometric figures, and to thereby improve learning effect.SOLUTION: A graphic display device comprises: a communication part 15 that inputs graphic information representing a graphic figure and a condition given to the graphic figure; a liquid crystal display part 21 that displays the graphic figure and condition based on the input graphic information; condition/basic graphic data 12b that plurally stores information on a condition relating to the basic graphic and an additional condition to be obtained from the condition; and a CPU 11 that searches for a basic figure having the condition matched from the basic figure stored in the condition/basic graphic data 12b with respect to a content displayed on the display part 21, acquires a candidate of the basic figure serving as an auxiliary graphic from a search result, prompts to designate the candidate of the basic figure serving as the acquired auxiliary graphic, receives the prompting input operation via a touch input part 22 and a coordinate input part 23, or a key input part 19, and causes the basic figure serving as the received auxiliary figure to be displayed together with the additional condition in a state where the basic figure is overlapped on a graphic displayed on the liquid crystal display part 21. |
