Using the pythagorean relationship

Using the pythagorean relationship

In the previous section, we have learned the Pythagorean Theorem. We will now apply the knowledge to answer questions involving compound polygons.
Basic concepts: Squares and square roots, Pythagorean theorem, Estimating square roots,
Related concepts: Determine square roots of rational numbers, Using exponents to describe numbers, Distance formula: d=(x2−x1)2+(y2−y1)2d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2},
