Geometry Test | 1. Two birds are flying toward a birdhouse that is halfway between them. The birds are at coordinates A (-4, 4) and B (10, -2). How far will each bird fly (to the nearest foot) to arrive at the birdhouse, if each grid represents 100 feet?: * | a.580 feet | b.762 feet | c.1,160 feet | d.1,523 feet | Please respond to the question above. | 2. The line segment CD is the diameter of a circle whose center is the point (2, 1). If the coordinates of C are (0, -2), find the coordinates of D.: * | a.(0, 4) | b.(4, 0) | c.(4, -2) | d.(4, 4) | Please respond to the question above. | 3. Write in standard form the equation of the line that passes through the point (3,-6) and is perpendicular to the line that passes through the points (1,3) and (6,-7).: * | a.y + 6 = 1/2(x - 3) | b.2x - y = 12 | c.-1/2x + y = -7.5 | d.x – 2y = 15 | Please respond to the question above. | 4. Which of the following groups of points are the vertices of a right triangle?: * | a.(2,2) (4,1) (4,6) | b.(1,1) (4,4) (7,2) | c.(2,6) (-4,3) (-3,0) | d.(1,1) (3,0) (0,-4) | Please respond to the question above. | 5. Find the area of the dark blue sector shown below. The radius of the circle is 4 units and the length of the arc (the curved edge of the sector) measures 7.85 units. Express answer to the nearest tenth of a square unit.: * | a.0.3 sq. units | b.15.7 sq. units | c.19.7 sq. units | d.50.3 sq. units. | Please respond to the question above. | 6.
