Exercise 55 Page 10

Use the Pythagorean Theorem.

10cm

Practice makes perfect

To find the missing side of the triangle, we will use the Pythagorean Theorem.

In the formula, a and b are the legs and c is the hypotenuse of a right triangle. We are given a triangle with a=6cm and b=8cm. Let's substitute these values into the formula.

a^2+b^2=c^2

SubstituteII

a= 6, b= 8

6^2+ 8^2=c^2
