In the figure on the right, xy and xz are tangents from an external point X. 1. Is XY congruent to XZ ? Why? A. No, because the two segments from the same exterior Point does not connect the circle with two points. 8. No, because the two segments from the same exterior point are not tangents on the circle. C. Yes, because the two segments from the same exterior point connects the two points on the circle. D. Yes, because the two segments from the same exterior point are tangents on the circle. 2. Is AXYW congruent to AXZW? Justify your answer. A. Yes, because of Hypotenuse leg theorem. B. Yes, because of Hypotenuse acute angle theorem, C. No, because the two sides of a triangle are not equal. D. No because they are not right triangles. 3. Suppose m zWXY- 40, What is the m zWXZ? B. 40 C. 50 A. 30 D. 60 4. If YW 15 and YZ - 20, what is the length of XW? B. 23 A. 22 C. 24 D. 25 5.

Use Desmos to draw a circle of radius R centered at (0,0). Take p to be the point (0,R + h) and have Desmos draw line segments L1 and L2 from p to the circle so that L1 and L2 are lines of sight from an observer at p to the horizon. Be sure to mark the points of intersection of L1 and L2 with C. Make a slider for h and see how the lines L1 and L2 change as h changes.
