Fun Examples of Triangles for Kids

📚 Quick Study Guide

• 📐 A triangle is a polygon with three sides and three angles.
• 📏 The sum of the angles in any triangle always equals 180 degrees.
• 🧮 Triangles can be classified by their sides: equilateral (all sides equal), isosceles (two sides equal), and scalene (no sides equal).
• 🧐 Triangles can also be classified by their angles: acute (all angles less than 90 degrees), right (one angle is 90 degrees), and obtuse (one angle greater than 90 degrees).
• 🍕 Everyday examples include pizza slices, road signs, and the sides of a pyramid.
