Animated Math Clip Art--Triangles--Scalene Triangle Construction

This animated GIF shows how to construct a scalene triangle using a compass and straightedge. The triangle has sides measuring 3 inches, 4 inches, and 5 inches. The construction involves drawing the longest side first, creating two intersecting arcs from each endpoint using their respective side lengths, and completing the triangle from the point of intersection.

This resource supports instruction aligned to CCSS.MATH.CONTENT.7.G.A.2 and can be used in lessons on triangle classification and geometric construction. The animation is ideal for illustrating that all three sides are unequal and for reinforcing the concept of triangle uniqueness.
