Pentagon A’B’C’D’E’ has been dilated by a scale factor of one-third which simply means that each x and y value has been multiplied by one-third to get the new coordinates.

### Monday, April 2

Common Core Standards and Extended Standards
8.G.2: Understand that a two dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

The Pythagorean Theorem has been used for thousands of years across the globe. The Pythagorean Theorem applies to right triangles. It states that the sum of the legs squared equals the hypotenuse squared. The legs are the vertical and horizontal sides of a right triangle. The hypotenuse is the longest side. It is also the diagonal side. The Pythagorean Theorem can be used to find the distance between any two points on a coordinate grid as well as to solve many real life math problems. For example, it can be used to solve for the distance (in blocks) to school in the problem above.
