Math Example--Polygons--Triangle Classification: Example 24

Topic

Triangles

Description

This example shows a triangle with angles labeled as x, 0.25x, and 1.1x. Solving for x, we find that all angles are less than 90°, classifying the triangle as acute.

Triangles are classified by their angle measures or side lengths, with acute triangles having all angles less than 90°. Reviewing examples like this helps students reinforce the criteria for classifying triangles based on angle sizes.

Seeing multiple worked-out examples builds students' confidence in applying classification rules and identifying triangle types based on consistent properties.

Teacher's Script: "By solving for each angle, we see all angles are less than 90°, so this is an acute triangle. Observing angle measures helps us use the correct classification."
