Have two geometric shaped objects on an ice rink. Let one of these objects move in a certain direction in the coordinate plane (horizontal axis x, vertical axis y) (let this direction be denoted by the vector (Ax, Av)) up to a and the other object remains stationary. If the direction is chosen correctly, the moving object will hit the fixed object according to the size of a (if it is large enough). This situation is represented in the image. If the blue triangle above is moved far enough in the direction indicated by the black arrow, it will hit the pink rectangle at the round point marked in black. Goal; To find the smallest a value that will ensure the collision while the shapes, positions and movement direction are determined. a) The triangle field, with inequalities x-y-1, x + y 1; If the quadrilateral is represented by inequalities x > 4, x 2, y 1; If the quadrilateral is represented by inequalities x > 4, x 2, y
