Sketch a figure from a net
👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

Visualizing Two-Dimensional Cross Sections of Cylinders
In this video, the teacher explains how to determine the shape of a cross section when slicing a three-dimensional solid. By analyzing whether the slicing plane intersects with straight or curved surfaces, students can visualize and...
