Exploring Dilation in Geometry

The video tutorial introduces the concept of dilation in geometry, explaining how it involves resizing objects. It provides two examples: one with a scale factor of three, enlarging a triangle, and another with a scale factor of one-third, reducing the triangle's size. The tutorial demonstrates the process of multiplying coordinates by the scale factor to achieve dilation and concludes with a prompt to subscribe for more math tutorials.

What does dilation in mathematics refer to?

• Making an object bigger or smaller

• Rotating an object

• Shifting an object's position

• Changing the color of an object
