**Review lines, line segments, rays and angles!!!**• You can’t answer any CRCT questions without knowing these definitions. • Review also: • Right angles • Acute angles • Obtuse angles • Parallel lines • Intersecting lines • Perpendicular lines**Solve:**• All of the following figures except one are part of a line. Which is not part of a line? • A. point • B. angles • C. segment • D. ray**Solve:**• What figures make an angle? • A. 2 segments • B. 2 lines • C. 2 rays • D. 2 points**Plane Figures**• Review polygons and their sides • Plane figures are flat!!! • Polygons are 3 or more sides and are closed • Regular polygons have all congruent sides • Irregular polygons do not have congruent sides.**Solve**• What do these shapes have in common? They all have 4 sides They are all rectangles They are all regular polygons They all have 2 right angles USE THE PROCESS OF ELIMINATION TO ANSWER THE QUESTION!!!**Solve**• What is the name of this figure? • A. triangle B. pentagon C. octagon D. hexagon**Solve**• This triangle is a(n) _________ triangle. • A. scalar B. scalene C. isosceles D. equilateral**Solve**• Greg drew a shape. The shape had multiple sides. All of the interior angle of the shape had a different measurement. Two of the sides were parallel. Which of these shapes could Greg have drawn? • A. triangle B. rhombus C. pentagon D. trapezoid • HINT: Interior means angles inside the shape. Draw a picture if needed. Make sure you draw 2 sides parallel.**Solve**• How many acute angles appear to be in this figure? • A. 4 B. 3 C. 2 D. 1**Solve**• How many obtuse angles does this figure have? • A. 6 B. 4 C. 2 D. 1**Solve**• William is going to add all the angles in a shape. Which of these shapes will have the smallest sum? • A. triangle B. square C. rectangle D. rhombus • HINT: DRAW A PICTURE FOR EACH ONE!!!!**Solve**• Which of these figures contains the largest angle? • A. rhombus B. rectangle C. right triangle D. equilateral triangle • HINT: DRAW A PICTURE OF EACH ONE OF THESE SHAPES.**Solid Shapes**• Review all solid shapes • Flat surfaces are faces. • The edges are where the faces meet • The vertex (vertices) are where the edges meet.**Solve**• Addison has a 3-dimensional shape. The shape has 5 faces, 6 vertices, and 9 edges. What shape does Addison MOST LIKELY have? • A. triangular prism B. rectangular prism C. isosceles triangle D. isosceles rectangle • HINT: C AND D ARE FLAT FIGURES!!! YOU CAN ELIMINATE THEM.**Solve**• Which figure is not shown here? • A. cone • B. cylinder • C. cube • D. rectangular prism**Solve**• Name the figure with 2 faces that are circles. • A. cylinder • B. sphere • C. cone • D. cube**Solve**• Name the figure whose only face is a circle. • A. pyramid • B. sphere • C. cone • D. cube**Solve**• If you cut a sphere right down the middle (think of a round fruit), what shape do you see? • A. square • B. circle • C. triangle • D. rectangle**Congruent and Similar**• Congruent means equal in every way!!! • These are congruent**Similar**• Similar is the same shape with the same properties, but probably not the same size. • These rectangles are similar.**Solve**• Which set contains congruent figures? • A. • B. • C.**Circles**• Review the following terms on the geometry powerpoint: • Circle • Diameter • Radius • Chord**Solve**• Jack ran on a circular track.
