The sum of two numbers is s. If one of the numbers is n, the second number can be expressed as?
I will be happy to critique your thinking or work.
what are polygons with the same size
To find the second number when the sum of two numbers is given, we can subtract the first number from the sum.
Let's say the sum of two numbers is "s" and one of the numbers is "n." The second number can be found by subtracting "n" from "s." So the expression for the second number is:
Second number = s - n
Now, moving on to your second question about polygons. Polygons that have the same size are called congruent polygons.
Congruent polygons are geometric figures that have the same shape and size. This means that all corresponding sides are equal in length, and all corresponding angles are equal in measure.
For example, if you have two triangles, and all sides of one triangle are equal to the corresponding sides of the other triangle, and all angles of one triangle are equal to the corresponding angles of the other triangle, then those two triangles are congruent.
Similarly, if you have two polygons, whether they are triangles, quadrilaterals, pentagons, or any other polygon, and all their corresponding sides and angles are equal, then those polygons are congruent.
