  1. Geometry Word Search and Scavenger Hunt

  2. Angle formed by two lines, or rays, which meet at a point called the vertex.

  3. Vertex • The point where two rays meet to form an angle.  Point A is the vertex of the angle. It can be used to name the angle with only one letter. A

  4. Degree • The unit used to measure the size of an angle. One degree represents 1/360 of a circle. The symbol is °.

  5. Acute Angle • An angle that measures between 0° and 90°. A <B or <ABC or <CBA B C

  6. Obtuse Angle • An angle which measures between 90° and 180°. D <O or <DOG or <GOD G O

  7. Right Angle • An angle which measures exactly 90°. C <A or <CAT or <TAC A T

  8. Straight Angle • A straight line which measures exactly 180°.

  9. Complementary Angles • two angles which add together to be 90°. B Y < JOY and <BOY are complementary angles. They form the right <JOB J O J

  10. Supplementary Angles • Two angles whose measurements add to 180°. R C J A <CAR and <JAR are supplementary angles. They form the straight <CAJ

  11. Vertical Angles • Formed by two intersecting lines which form two pairs of opposite angles which are congruent (equal). <‘s 1 and 3 are vertical and <‘s 2 and 4 are also. 1 2 4 3

  12. Adjacent Angles • Two angles that have the same vertex, share a common side, and do not overlap. S M < BUM and < SUM are adjacent angles. B U

  13. Corresponding Angles • Angles that have the same position on two different parallel lines that have been cut (intersected) by a third line (a transversal). <1 and <5 <2 and <6 <3 and <7 < 4 and <8 1 2 3 4 5 6 8 7

  14. Parallel Lines • Two lines in the same plane that never get any closer to each other, they never meet or intersect. m l l  m

  15. Perpendicular Lines • Lines that intersect to form right angles. l l  m m

  16. Triangle • A polygon with three sides.

  17. Right Triangle • A triangle with exactly one right angle.

  18. Acute Triangle • A triangle with three acute angles.

  19. Obtuse Triangle • A triangle with exactly one obtuse angle.

  20. Scalene Triangle • A triangle with no congruent sides.

  21. Isosceles Triangle • A triangle with exactly two congruent sides.

  22. Equilateral Triangle • A triangle with all sides congruent.

  23. Polygon • A simple closed figure formed by three or more line segments.

  24. Quadrilateral • A polygon with exactly four sides.

  25. Pentagon • A polygon with exactly 5 sides.

  26. Hexagon • A polygon with exactly six sides.

  27. Heptagon • A polygon with exactly seven sides.

  28. Octagon • A polygon with exactly eight sides.
