Unit 1: Right Triangles and Trigonometry Target 1.3 Determine if a triangle is right, acute or obtuse by its side lengths (7.2)

The Triangle Inequality Theorem states that the sum of any two sides of a triangle must be __________________ the third side. Look what happens if the sum of two sides are NOT longer than the third… In other words, the ____________ of the two short sides have to be ___________________ than the third side. Is it possible to construct a triangle with the given side lengths? Explain. 4, 6, 9 10, 15, 10 3, 4, 7

In construction, builders use the Pythagorean Theorem to determine if a frame is “square” or not. You measure the height and width of a door frame to be 72 inches and 21 inches, respectively. The diagonal is 75 inches. Is the door frame “square”? (In other words, do you have a right triangle?)

Tell whether the triangle is a right triangle. Justify your answer.

If a triangle is not right, it is either acute or obtuse If a triangle is not right, it is either acute or obtuse. By testing the Pythagorean Theorem, we can use the side lengths to classify a triangle.

First, determine if the three sides can form a triangle First, determine if the three sides can form a triangle. Then, if they can, determine if that triangle that is right, acute, or obtuse. Justify your answer.

Graph the points A, B, and C. Connect the points to form a triangle Graph the points A, B, and C. Connect the points to form a triangle. Decide whether the triangle is acute, right, or obtuse. Pg. 444: 5-19(odds), 27, 35, 36
