Final Review Finally Here is a set of practice problems to prepare you for the final exam for Geometry High School credit. The score on this test is 25% of the grade that you will take to high school. The test is broken up into calculator and non-calculator sections. You will be able to use the calculators in my classroom and the PARCC reference sheet for the final. Be careful to not use a calculator if you are not required. You will also be allowed to graph on a separate sheet of paper during the final. If you want to know the lowest score you can receive, enter your quarter grades (as decimals) and desired grade into the formula below: Note: If the number is greater than 1, you cannot receive your desired grade even if you score a perfect on the final. PARCC practice test is also a great resource for practice: http://parcc.pearson.com/practicetests/math/ Non-Calculator Section Practice Problems 1. Find the missing sides of these triangles. 2. Identify the axis of symmetry for the following figure. 3. What is the measure of the minor arc AB in radians? 4. The equation describes a circle. Determine the coordinate of the center of the circle. If the radius is 10, what is the value of b? 5. What is the midpoint of a line segment with endpoints at coordinates (3, 5) and (-1, -7)? 6. A rectangle will be rotated 360° about a line which contains the intersection of the diagonals and is parallel to one of the sides. What three-dimensional shape will be created as a result of the rotation? 7. Find the measure of the arc starting at point A and rotation counter-clockwise in degrees. A Calculator Section Practice Problems 1. Determine the measures of all the angles in this diagram given angle XOP = 125 degrees. 2. Given triangle ABC and the following list of information, find the measure of angle ACZ. a. Point Z is located on line AB b. Measure of angle A is 60 degrees. c. Measure of angle B is 20 degrees. d. Line CZ is perpendicular to line AB 3. Let and , what does equal in terms of x and y? 4. The triangle will be rotated 180° clockwise about the point (-2,5) to create triangle A'B'C'. What are the coordinates of the points A', B', and C'? Does the perimeter and area change under this transformation? 5. The equation defines a circle in the xy-coordinate plane. What is the center of the circle? 6. Given a pyramid with a height of 13 meters and a rectangular base w meters wide by l meters long and a pyramid with the same base and a height of 1 meter. What is the difference in the volumes in terms of the base areas? 7. Find the height of the tree in this diagram. 8. Triangle ABC has vertices at A(2,4), B(5,1) and C(3,2) in the coordinate plane. The triangle will be reflected over the x-axis and then rotated 180° about the origin to form Triangle A'B'C'. What are the coordinates of A', B' and C'? 9. What is the surface area of a cylindrical can that has a height of 40 cm and a diameter 14 cm? 10. If the circle in this picture is 10 in. in diameter, what is the area of the square with vertices on the circle? 11. If point A is located at (1,-2) and is reflected about y = 1 to form A’, what quadrant contains A’ and what are the coordinates of A’? 12. Find x. 13. Find the length AB. 14. If and and OB = 25, find angle ACB and BC. 15. Describe the steps to constructing a perpendicular bisector. 16. If x = 13, what is the measure of angle A? 17.
