The height of an isosceles triangle is 12cm. The base of the triangle is 18cm. Work out the length of the equal sides

The length of the equal sides is 15 centimeters.

Step-by-step explanation:

Since, base and height of the triangle are perpendicular to each other. In an isosceles triangle, the value of each equal length (), measured in centimeters, can be determined by the following Pythagorean identity:

(1)

Where:

- Base of the triangle, measured in centimeters.

- Height of the triangle, measured in centimeters.

If we know that and , then the value of each equal length within the isosceles triangle is:

The length of the equal sides is 15 centimeters.
