1) Consider the following: A D B Let å denote the defect of a triangle. One of the following two statements can be proved in Neutral Geometry and the other cannot. Prove the one that can be proved and explain why the other cannot be proved in Neutral Geometry: S: 8(ACD) < 8(ABC) T: 8(ACD) ≤ 8(ABC)

1. Find the perimeter of a triangle with vertices S(4, 5), T(-2, -3), and W(5, - 4). 2. How is the Pythagorean theorem related to the distance formula?

1. What are the parts of HL theorem? 1. It appears from the name of the HL Theorem that you actually need to know only two parts of a triangle in order to prove two triangles congruent. Is this the case? o Yes, you only need to know the hypotenuse and a leg of a triangle. O No, you actually need to know two sides and an angle, because the triangle must be a right triangle. O No. you actually need to know three sides of the triangle. O No, you actually need to know two angles and a side. A D Type here to search W DELL F2 F3 F4 F5 F6 E7 F8 F9 F10 ! 23 $ & 2 3 4 6 8.
