Geometry Midterm Exam Name: ____________________________ Student Number: ____________________ Answer the questions below. Make sure to show your work and provide complete geometric explanations for full credit. 1. Use the above figure to answer the following questions. a. Name three points that are collinear B,D,A b. Name four coplanar points A,C,D,E c. What is the intersection of plane P and plane R? A,D,B d. Name a point that lies on both plane P and plane R D e. Name plane P and two more ways E,D,C or A,C,E 2. To the nearest tenth, find the perimeter of ABC with vertices A(2,4), B(-2,1) and C(2,1). Show your work. The base of the tiangle is line AB. Since the base lies on the x-axis its length = 2-(-2) = 2+2 = 4units. The height lies on the y-axis on the line AC. Length = 4-1 = 3units. The hypotenuse, BC = 4 2 + 32 =5units Perimeter = 5+4+3 = 12 units. Geometry Midterm Exam Name: ____________________________ Student Number: ____________________ Answer the questions below.
