A triangle with all three sides labeled as 9.

Topic

Triangles

Description

This example shows a triangle with side lengths all equal to 9. Since all sides are congruent, the triangle is classified as equilateral.

Triangles can be classified based on side or angle properties. An equilateral triangle has all sides and angles congruent. Viewing multiple examples reinforces students’ understanding of these classifications and enhances their ability to recognize triangle properties.

Seeing several worked-out examples helps students understand and apply the rules consistently for classifying triangles.

Teacher's Script: "Here, all sides are equal, so we classify this triangle as equilateral. Observing equal sides helps us apply the correct classification."
