Back Points, Lines, and Planes for $400 Draw two adjacent angles Answer 1 2 Back Points, Lines, and Planes for $500 Define: Polygon Answer Polygon - A simple, closed, 2-D figure made up of three or more line segments. Back Polygons for $100 Give every possible name for a square Answer Square, rhombus, rectangle, parallelogram, quadrilateral, polygon Back Polygons for $200 Give the best name for the figure with the following properties: Opposite sides are parallel and congruent Answer Parallelogram Back Polygons for $300 Give the best name for the figure with the following properties: The diagonals bisect each other and are perpendicular Answer Rhombus Back Polygons for $400 What is the formula for the number of degrees in any polygon and where does it come from? Answer Degrees = (n-2)*180, where n is the number of sides in the figure It comes from drawing all the diagonals from one vertex (breaking the shape into triangles) Back Polygons for $500 Quadrilaterals are broken into three groups for naming based on one property. What is that property? Answer The number of parallel sides Back Congruence for $100 What are the three ways to determine if two triangles are congruent using only three pieces of information? Answer SSS, ASA, SAS Back Congruence for $200 What does CPCTC stand for? Answer Corresponding parts of congruent triangles are congruent. In other words, if two triangles are congruent then the angles and sides that are in the same position on each triangle are also congruent. Back Congruence for $300 Are the two triangles congruent? If so, how do you know? Answer Yes, they are by SAS. Two sides are given as congruent and the included angles are congruent because they are vertical angles Back Congruence for $400 Are the two triangles congruent? If so, how do you know? Answer Not necessarily. Although they could be congruent, there is not enough information to tell for sure. SSA is inconclusive. Back Congruence for $500 Are the two triangles congruent? If so, how do you know? Given: AB bisects angle A A D C B Answer Yes, they are congruent by SAS. One pair of sides are congruent (given). Side AB is congruent to itself, and the angles CAB and DAB are congruent (definition of angle bisector. Back Circles for $100 Where does pi come from? Answer The circumference of a circle divided by the diameter of a circle. Back Circles for $200 Define: Circle Answer The locus of all points equidistant from a given point (the center) Back Circles for $300 What is a central angle? Answer Any angle whose vertex lies on the center of the circle Back Circles for $400 The circumference of a circle is 10cm. To the nearest tenth, what is the radius of the circle? Answer C = 2(pi)*r 10 = 6.28r r = 1.6cm Back Circles for $500 Given that a sector is 55% of a circle, how many degrees are in the central angle of the sector? Answer 0.55 = 360x x = 198 degrees Back Transformations for $100 What is the name of the picture of a figure prior to a transformation being done on it? Answer The pre-image Back Transformations for $200 What are the two pieces of information you need to be given in order to rotate a figure. (assume the figure is already given) Answer The angle of rotation and the center of rotation Back Transformations for $300 Use arrow notation to describe a translation of 5 units up and 2 units to the left Answer (x, y) -> (x – 2, y + 5) Back Transformations for $400 Reflect the following figure over the line y = -1 Answer Back Transformations for $500 Rotate the following figure 270 degrees about the origin: Answer Back
