Math Example--Polygons--Triangle Classification: Example 15

Topic

Triangles

Description

This example presents a triangle with two angles labeled 60° and an unknown angle labeled x. Solving for x, we find it to be 60°, making all angles congruent and classifying the triangle as equilateral.

Triangle classification can be determined by side length or angle measures. An equilateral triangle has all equal sides and angles. Observing multiple examples helps students apply these criteria consistently when classifying triangles.

Seeing several worked examples helps students gain confidence in identifying triangles by recognizing congruent angles or sides.

Teacher's Script: "By solving for the missing angle, we see all angles are the same, classifying this triangle as equilateral. Observing angle sizes helps us use the correct classification."
