Math Example--Polygons--Triangle Classification: Example 8

An equilateral-looking triangle with two angles labeled as 60° each.

Topic

Triangles

Description

This example shows a triangle with two angles, each measuring 60°. Since two angles are congruent, this triangle is classified as isosceles.

Triangles can be categorized by side or angle properties. Isosceles triangles have two equal sides or two equal angles, as illustrated here. This collection of examples allows students to observe classifications and understand patterns in triangle properties.

Examining multiple examples helps students confidently identify triangle types based on consistent characteristics.

Teacher's Script: "Here, two angles are the same, so we classify this as an isosceles triangle. Matching angles or sides helps us apply the correct classification."
