In this activity, students will draw figures in one- and two-point perspective, comparing and contrasting the two types of drawings. They then create an isometric drawing and compare it to the other drawings.
In Problem 1, students explore perspective drawings from a one-point perspective when drawing a prism. They use a vanishing point A to assist them in constructing a prism.
They use the Segment tool to draw segments that join a vertex of the prism to the vanishing point. These segments are called vanishing segments. After completing the prism, students hide the vanishing segments that are joined to the vanishing point. Students can identify parallel, intersecting, and skew lines. They can move the prism around and count its faces, vertices, and edges.
In Problem 2, students explore a two-point perspective. They follow a similar procedure as in problem 1. After completing the prism students hide the vanishing segments and study the figure.
Students take some time to drag edges, vertices, and vanishing points to observe how the prism changes as they do so.
In Problem 3, students explore isometric drawings. After completing an isometric drawing of a prism, students will compare it to the perspective drawings.
