GEOMETRY SOL 5.13 Geometry 1 What is this shape called? Answer Parallelogram Geometry 2 What is the DEFINITION of a parallelogram? Answer A quadrilateral in which both pairs of opposite sides are parallel. Geometry 3 What is this shape called? Answer Square Geometry 4 What is the definition of a square? Answer A rectangle with four congruent sides Geometry 5 What is this shape called? Answer Rectangle Geometry 6 What is the definition of a rectangle? Answer A parallelogram with four right angles Geometry 7 What is this shape called? Answer Triangle Geometry 8 What is the definition of a triangle? Answer A polygon with three sides. Geometry 9 What is this shape called? Answer Rhombus Geometry 10 What is the definition of a rhombus? Answer A parallelogram with FOUR congruent sides. Opposite angles are also congruent. Geometry 11 What is this shape called? Answer Kite Geometry 12 What is the definition of a kite? Answer A quadrilateral with two distinct pairs of adjacent, congruent sides Geometry 13 What is this shape called? Answer Trapezoid Geometry 14 What is the definition of a trapezoid? Answer A quadrilateral with exactly one pair of parallel sides. Geometry 15 What type of triangle is this? Answer A right triangle. Geometry 16 What is the definition of a right triangle? Answer A right triangle has one right angle, and two acute angles. Geometry 17 Are these two shapes congruent? Answer YES, they are exactly the same size and shape. Geometry 18 Are these two shapes similar? Answer YES, they have the same shape but not the same size. Geometry 19 Are these two shapes non-congruent? Answer Yes, they are the same shape, but not the same size. Geometry 20 Can two shapes be both non-congruent and similar? Answer Yes. Both definitions mean they have the same shape, but not the same size. Geometry 21 What type of angle is this? Answer A Right Triangle (One 90° angle) Geometry 22 What type of angle is this? Answer An ACUTE angle (less than 90°) Geometry 23 What type of angle is this? Answer An obtuse angle (greater than 90° but less than 180°) Geometry 24 What type of triangle is this? Answer An ACUTE triangle An acute triangle has three acute angles. Geometry 25 What type of triangle is this? Answer An obtuse triangle An obtuse triangle has one obtuse angle and two acute angles. Geometry 26 Is the second shape a REFLECTION (Flip) of the first shape? Answer Yes A reflection is a transformation in which a figure is “flipped” over a line of reflection “A mirror image” Geometry 27 Is the second shape a REFLECTION (Flip) of the first shape? Answer YES Geometry 28 Is the second shape a REFLECTION (Flip) of the first shape? Answer NO Geometry 29 Is the second shape a ROTATION (turn) of the first shape? Answer YES The image or shape is a transformation in which the image is “turned.” It has not been changed in any other way. Geometry 30 Is the second shape a ROTATION (turn) of the first shape? Answer No The second arrow has not been changed in any way. Geometry 31 Is the second shape a TRANSLATION (slide) of the first shape? Answer YES A transformation in which an image is formed by moving every point in a figure the same distance and in the same direction. Geometry 32 Is the second shape a TRANSLATION (slide) of the first shape? Answer No The second figure has not been moved the same distance and in the same direction. Geometry 33 What does “parallel” mean? Answer Two lines that continue indefinitely without intersecting. Geometry 34 What does “parallel” mean? Answer What does “congruent” mean? Geometry 35 “SAME” Geometry 36 What is this shape? Answer A cube A solid with 6 congruent square faces and 12 edges where every face is a square and every edge is the same length. Geometry 37 What is this shape? Answer A cylinder A three dimensional shape that has two congruent and parallel circular sides joined by a curved surface. Geometry 38 What is this shape? Answer A cone A solid with a circular base and a curved surface with one vertex (point). Geometry 39 What is this shape? Answer Rectangular prism Is a solid in which all six faces are rectangles with three pairs of parallel, congruent, opposite sides. Geometry 40 What is the mathematical name for this shape? Answer A square pyramid A 3D shape whose base is a square and other faces are triangles that share a common vertex (point).
