## Perspective

#### Activity Overview

Students draw figures in one and two-point perspective and compare and contrast the two types of drawings. They then create an isometric drawing and compare it to their drawings in perspective.

#### Key Steps

• In Problem 1, students use Cabri™ Jr. to explore perspectives from a one-point perspective when drawing a prism. They use the Segment tool to draw segments that join a vertex of the prism to a vanishing point.

• After completing the prism, students hide the segments (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.
