MTH 116 Final Exam with correct answers 100% 2026 Complementary Angles - Correct Answer Add up to 180 degrees Supplementary Angles - Correct Answer Add up to 90 degrees Vertical Angles - Correct Answer Angles across from each other in an X Adjacent Angles - Correct Answer Angles next to each other Shannon and her small group are trying to find ways to sort a set of quadrilaterals. They identify two groups and begin to sort. When they get down to it, they have quadrilaterals that belong to each group, but they also have a few (not all) that belong to BOTH groups. What might have been their groups? - Correct Answer Group 1: Shapes with at least one set of parallel sides, Group 2: Shapes with at least one right angle (T/F) A quadrilateral can be both a kite and a trapezoid - Correct Answer True Using a three-by-three geoboard, there are ____ unique (non-congruent) quadrilaterals that can be made that can be called trapezoids - Correct Answer 9 What is TRUE about polygons and their angle sums? - Correct Answer All pentagons have an angle sum of 540 degrees How many of the quadrilaterals from our sort can be made using the RhombusMaker? - Correct Answer 5 The sizes of three interior angles of a quadrilateral are 65 degrees, 35 degrees, and 60 degrees. What is the size of the fourth angle of the quadrilateral? - Correct Answer 200 degrees A prism has 42 edges. How many total faces does it have? - Correct Answer 16 (T/F) Every n-gonal pyramid has has n + 1 faces - Correct Answer True (T/F) It is impossible for the number of edges, faces, and vertices to all be odd numbers, no matter what type of polyhedron you have. - Correct Answer False What is the sum of the number of edges and the number of vertices of an octagonal pyramid? - Correct Answer 25 A prism with 9 faces has ________ vertices and ______ edges - Correct Answer 14, 21 Of the six types of quadrilaterals that we have discussed in class: kite, trapezoid, parallelogram, rectangle, rhombus, and square, which type always has rotational symmetry, but only sometimes has reflectional symmetry? - Correct Answer Parallelogram The point (-4, 2) has been reflected over the y-axis. What are the coordinates of the point's image? - Correct Answer (4,2) The point (3, -1) has been reflected over the x-axis. What are the coordinates of the point's image? - Correct Answer (3,1) The point (-2. -1) has been rotated 270 degrees counter clockwise about the point (0,0). What are the coordinates of the point's image? - Correct Answer (-1,2)
