If you have a teen learning Geometry, you probably know that there are a lot of formulas and mathematical concepts involved when it comes to solving problems.
Fortunately, there are several mnemonics that have been developed by educators that can help your teen memorize these important aspects of Geometry.
Below are six memory tricks you can share with your teen. Hopefully they will make his journey through geometry easier.
Geometry Mnemonics
The Measure of an Angle in a Right Triangle
This memory trick for finding the measure of an angle in a right triangle has been around a while and you’ll probably recognize it.
SOH-CAH-TOA
SOH: Sine = Opposite divided by the Hypotenuse
CAH: Cosine = Adjacent divided by the Hypotenuse
TOA: Tangent = Opposite divided by the Adjacent
Isosceles Triangle
If your teen has difficulties remembering what an isosceles triangle is, he can sing this song to the tune of “O Christmas Tree.”
O, isosceles, o, isosceles,
Two angles have
Equal degrees.
O, isosceles, o, isosceles
You look just like
A Christmas tree.
Area of a Circle
The formula for the area of a circle is:
A = Πr2
This grammatically incorrect phrase will help your teen remember it.
Apple pie are square.
Circumference of a Circle
The formula for the circumference of a circle is:
C = ΠD
Another kind of pie will help your teen remember it.
Cherry Pie Delicious!
Circumference and Area of a Circle
This little poem teaches the formulas for both the circumference and area of a circle.
Tweedle-dee-dum and Tweedle-dee-dee,
Around the circle is pi times d,
But if the area is declared,
Think of the formula pi “r” squared.
First Eight Digits of Pi
Does your teen like to memorized the digits of pi? He can learn the first eight by counting the letters of each word in this phrase.
May (3) I (1) have (4) a (1) large (5) container (9) of (2) coffee (6)?
