Pythagorean Theorem
... Which number goes where? You need to identify the hypotenuse. It’s the one opposite of the right angle. The hypotenuse is always going to be the c in the formula. Since we do not know the value of c, it stays as c in the formula. Does it matter whether we use a = 8 or 15? No. Let’s use a = 8 and b = ...

4.1 – Classifying Triangles
... Classify a triangle in the coordinate plane Now you try… Classify ΔABC by its sides. Then determine if the triangle is a right triangle. The vertices are A(0,0), B(3,3) and C(-3,3). Step 1: Plot the points in the coordinate plane. ...

right triangle
... Pythagorean Theorem • Recall that a right triangle has a 90° angle as one of its angles. • The side that is opposite the 90° angle is called the hypotenuse. • The Pythagoreans theorem says that the square of the hypotenuse is equal to the sum of the squares of the legs. c2 = a2 + b2 a ...
