<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

AB = 3 units, AC = 4 units. Using Pythagoras theorem:

BC² = 3² + 4²

BC = 5 units

AE = 6 units, AD = 8 units. Using Pythagoras theorem:

DE² = 6² + 8²

DE = 10 units

From the two triangle, we can see that triangle ADE is a dilation of triangle ABC by a scale factor of 2.
