Math Example--Polygons--Triangle Classification: Example 11

A triangle with two congruent sides labeled x and one different side labeled y.

Topic

Triangles

Description

This example shows a triangle with two sides labeled as x and a third side labeled y. Because two sides are congruent, the triangle is classified as isosceles.

Triangles can be classified by their side lengths or angle measures. An isosceles triangle has two equal sides or angles, as seen in this example. Reviewing a series of examples helps students understand these classifications and recognize patterns in triangles.

Seeing multiple worked-out examples allows students to apply classification rules more effectively, strengthening their ability to identify triangle types accurately.

Teacher's Script: "In this triangle, two sides are the same, so we classify it as isosceles. Observing the side lengths helps us make the right classification."
