It is not enough if it just visually coincides with the correct answer.Section 9.15. Try to prove that your construction satisfies the statement of the problem. Switch to the Explore mode (the orange button) and take a look how the answer depends on point configuration. But, for example, a midpoint or a tangent point can never be red. In general, you do not need to avoid them since some optimal solutions are impossible without red points. A correct construction should satisfy the statement of the problem for any configuration of points and figures.Ĭheck the red points. Select the Hand tool and try to drag different points. For example, you could forget to set a point in one of the ends of a line segment. ![]() Make sure that the required object is really constructed. You can also review definitions in our glossary by tapping "?" under the statement. To review it tap a preview card in the top left corner of the game screen. Read carefully the statement of the problem. Most probably your solution is not accepted because it is just an approximation. The app just verifies that the target object is present on the screen. There are no built-in solutions in Euclidea.
