This is an interactive angle estimation exercise. Students view randomly displayed angles on the screen, estimate their measures by eye, input their answers, and receive immediate validation. The core mathematical concepts include angle measurement, estimation skills, and the relationship between angles and rotation. Construction highlights: using Sequence and Random commands to generate random angles, Angle command to draw the angles to be estimated, Textfield for user input, conditional logic to verify answers, and Text command to display dynamic feedback. Suitable for middle school math classes, self-assessment practice, or homework, helping students develop strong angle perception skills.

AI Drawing Prompt Reference

Draw a diagram with four circles, each representing an angle. The lines connecting the centers of the circles represent the relationships between the angles. There are four circles, each representing a 90-degree, 180-degree, 270-degree, and 360-degree angle. The radii of the circles are equal, and the distances between the centers are also equal. Draw the four circles and connect the centers of each pair to form a quadrilateral.
