Clarifying the Equation Question
The center of the hanger represents an equal sign, since both sides of the hanger are equal.
Given different coloured triangles and shapes, we can assign a variable to each of them.
Assigning Variables
Let one green triangle be equal to
.
Let one blue square be equal to
Let one red circle be equal to
.
Let one yellow pentagon be equal to
.
Creating Terms
On the left side of the hanger/equation, there are 3 green triangles. This means that one of our terms in our equation will be
.
Under the triangles on the left side is 1 blue square. This means that the next term could be
, or just
.
Next is 2 red circles ⇒
And finally are 3 yellow pentagons ⇒
To sum up the left side as an expression, we can write all the terms we have just written as a sum:
Now, after doing the same procedure for the right side of the hanger, we get:
Writing the Equation
For now, we only have two expressions representing the two sides of the hanger:
Left:
Right:
To turn these into an equation, we must have an equal sign.
Remember that both sides of the hanger are equal. Knowing this, we can state the following:
Left side = Right side
