What is the sum of the exterior angles of a triangle? Use the fact that the sum of the interior angles of a triangle is 180° and the fact that the measure of a straight angle is 180° to justify your answer.
Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is 3 × (180° – 180°) = 0°.
Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is (3 × 180°) – 180° = 360°.
Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is (3 × 180°) + 180° = 720°.
Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is 3 × (180° + 180°) = 1080°.
A proof of the Pythagorean Theorem is shown below. What reason BEST justifies statement 9?

The Pythagorean Theorem
Which of the following would PROVE the Pythagorean Theorem?
Let a = 5 and b = 12 and use the equation a2 + b2 = c2 to solve for the value of c.
Show that the equation a2 + b2 = c2 holds true for a = 5, b = 12, and c = 13 and when a = 7, b = 24, and c = 25.
Set two different expressions for the area of a figure equal to each other and manipulate algebraically to show a2 + b2 = c2 .
Assume a2 + b2 ≠ c2 and show a = 5, b = 12, and c = 13 is a counterexample for the statement.
Michelle is composing a proof of the Pythagorean Theorem using the figure. What expression is her best option of what to put as the left side of the equation in Step 2 to advance her proof? 1/2 ab + 1/2 ab + 1/2 c2 = 1/2 (a + b)(a + b) _______ = 1/2 a2 + ab + 1/2 b2
1/2 c2
ab + c2
1/2 a2 + 1/2b
