Math Example--Polygons--Triangle Classification: Example 10

A triangle with two sides labeled 10 and one side labeled 8.

Topic

Triangles

Description

This example presents a triangle with side lengths of 10, 10, and 8. Since two sides are congruent, the triangle is classified as isosceles.

Triangle classification can be determined by side lengths or angle measures. Isosceles triangles have two equal sides or angles. Reviewing different examples assists students in identifying these types based on side or angle properties.

Seeing multiple worked-out examples reinforces students’ ability to classify triangles by consistently applying classification rules.

Teacher's Script: "Here, two sides are the same length, so we classify this as an isosceles triangle. Observing side lengths helps us apply the correct classification."
