    Αναπτύγματα στερεών

    Οι ασκήσεις με αναπτύγματα απαιτούν διαδοχικά νοερά διπλώματα, διατηρώντας τις θέσεις και τα σημάδια των εδρών. Ενεργοποιούν τον χωρικό μετασχηματισμό, την οπτική διάκριση και την οπτικοχωρική μνήμη εργασίας. Parameters adjust to the level and the task.

    Example

    Άσκηση 1

    Ποιο στερεό σχηματίζεται όταν διπλωθεί αυτό το ανάπτυγμα;

    AΤετραγωνική πυραμίδα
    BΤριγωνική πυραμίδα
    CΚώνος

    Άσκηση 2

    Ποιο στερεό σχηματίζεται όταν διπλωθεί αυτό το ανάπτυγμα;

    AΚύλινδρος
    BΤριγωνικό πρίσμα
    CΟρθογώνιο παραλληλεπίπεδο

    A generated instance. Parameters such as difficulty, size, and symbol set are adjustable.
