A triangle with three equal angles of 60 degrees.

Topic

Triangles

Description

This example shows a triangle with three angles, each measuring 60°. Since all angles are equal, the triangle is classified as equilateral.

Triangle classification can be based on side lengths or angle measures. An equilateral triangle has all angles congruent. Reviewing examples like these helps students understand classification rules based on triangle properties.

Multiple examples reinforce students' ability to identify triangle types consistently by observing angle or side characteristics.

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