Dive into the fundamentals of geometry with this comprehensive guide to acute angles and related concepts. An acute angle is defined as being more than 0 degrees and less than 90 degrees. This resource covers essential terms such as adjacent angles, bisecting an angle, congruent figures, and perpendicular lines, among others. Explore the properties of various angles, including obtuse, right, and straight angles, while gaining insights on transformations like reflection and rotation. Perfect for building a strong foundation in geometry!

  1. Dane’s Vocab Unit 5

  2. Acute angle:A acute angle is more then 0 degrees and less then 90 degrees

  3. Adjacent anglesangles that are next to each other

  4. AxisEither of the to number lines that intersect to form a coordinates grid

  5. Bisecting an angleand angle cute in half

  6. Concentric circlesCirclesthathavethesame center

  7. Congruent figuresHaving the shape and size

  8. Consecutive anglesTo angles in a polygon the have that share a common side

  9. Corresponding angles or sidesHaving the same relative position in similar or conglutinate figurs

  10. InscribedIn side of

  11. IsometryA transformation such as a translation(slide) reflection(flip) or rotation(turn) that changes the position or orientation of a figure but does not change its size or shape

  12. Line of reflectiona line halfway between a figure and its reflected image

  13. Mid pointA point halfway between two other points. The mid point of a line segment

  14. Obtuse angleA angle that over 90 degrees and less that 180 degrees

  15. Ordered number pairTwo numbers that are used to locate a point on a coordinate grid.

  16. ParallellineNevermeeting and alwaysthesamedistanceapart

  17. PerpendicularMeeting at rightangles, lines , rays ,line segments and planes thatmeet at rightangles

  18. Perpendicular bisectorA line segmentthatbisectstheside of a triangle

  19. Preimagea geotrical figure thatissomehowchangedtopurduce a nother figure

  20. Reflectiontheflipping of a figure over a line so theimageis a mirriorimage of theoriganal

  21. ReflexangleA angleover 180 degrees

  22. Right AngleAn angle that is a perfect 90 degrees

  23. RotationA movment of a figure around a fixed point or axis

  24. SectorA section of a percent circle

  25. Straight angle A angle that measure a perfect 180 derees

  26. Supplementary anglesTwo angles whose measures total 180 degrees

  27. TransformationSomething done to geometric figure that produces a new one

  28. TranslationA movement of a figure crossed a straight line

  29. TransversalA line that intersects two or more lines

  30. VertexThe point where a rays of an angle

  31. Vertical anglesWhen two lines intersect,the angle that do not have a common side.
