Question 687104
Draw a right triangle. One of the legs measures 8cm. The other leg measures 6cm. What is  the length of the hypotenuse?

I can't really draw a right triangle for you here, but the Pythagorean Theorem helps us to find the hypotenuse: (leg)^2+(other leg)^2=(hypotenuse)^2
Usually, we use a and b for the legs and c for the hypotenuse.
{{{highlight(a^2+b^2=c^2)}}}
{{{8^2+6^2=c^2}}}
{{{64+36=c^2}}}
{{{100=c^2}}}
{{{sqrt(100)=sqrt(c^2)}}}
{{{10=c}}}
The hypotenuse is 10 cm.

Happy Calculating!
