Math Example--Polygons--Triangle Classification: Example 3

A triangle with side lengths 12, 18, and x.

Topic

Triangles

Description

This example shows a triangle with side lengths of 12, 18, and x, where x is not equal to 12 or 18. The triangle is classified as scalene because all three side lengths are different.

Triangles are categorized by side length or angle. Scalene triangles, with all sides unequal, demonstrate a key classification type. Multiple examples help students recognize classification patterns for triangles based on side length or angle measure.

Observing various worked-out examples reinforces consistent application of classification criteria, building student confidence in identifying triangle types.

Teacher's Script: "Since each side length is different, we can classify this triangle as scalene. Observing the lengths lets us apply the correct classification."
