Triangle method to solve equations
By Marie Lyle
Science Equations
d=st
Distance=speed x time
V=IR
Voltage=Current x
F=ma
Resistance
Force=mass x
acceleration
Mass=density x volume
m=dv
Set up the triangle for the distance
equation. D=ST
The variable on the left (D) goes on top.
The variables on the right (S and T) go on the bottom.
Plug in the given values
If the given values are next to each other (S and T)
multiply to solve for D.
If the given values are above one another, divide the
top number by the bottom number to solve for S or T.
Hint: Cover the unknown. Then
multiply or divide to solve.
Any equation in the a=bc format
can be solved with a formula
triangle
Watch this animation to see how it works.
