Practice makes perfect

We are asked to choose the best of the given terms to complete a definition.

The of a number is a factor that gives the number when multiplied by itself.

Let's take a look at the given terms.

cc cube root & diagonal isosceles triangle & perimeter right triangle & square root To help us choose the term that best fits the definition, let's recall what each of the terms means.

Cube Root The cube root of a number is the number that, when raised to the power of 3, gives the original number.
Diagonal The diagonal of a polygon is a segment that connects two non-adjacent vertices.
Isosceles Triangle An isosceles triangle is a triangle with two congruent sides.
Perimeter The perimeter is the distance around a figure.
Right Triangle A right triangle is a triangle that contains a right angle.
Square Root The square root of a number is a number that, when squared, gives the original number.

The square root of a number can be squared to give the original number. Note that squaring a number is the same as multiplying it by itself. Because of this, we know that the term square root best fits the given definition.

The square root of a number is a factor that gives the number when multiplied by itself.
