    Vocabulary Report

    • perimeter -

      The distance around the outside of a shape

    • congruent -

      The same shape and size

    • area -

      The amount of space inside the boundary of a two dimiensional shape

    • symmetric -

      One side of a shape is exactly the same as the other

    • reflection (flip) -

      An image or shape as it would be seen in a mirror

    • line of symmetry -

      The imaginary line of the image where both halves match exactly

    • translation (slide) -

      To move a shape without rotating or flipping

    • square unit -

      The number of little squares used to measure the area inside a shape

    • rotation (turn) -

      A circular movement where the central point stays fixed and everything else moves around that point

    • similar -

      Having the same shape but not necessarily the same size

    • polygon -

      A two dimensional shape with straight sides

    • point -

      An exact location or position

    • ray -

      A line with a start point but no end point (it goes to infinity)

    • line -

      Straight, thin continuous mark extending in both directions without end (infinitely)

    • line segment -

      A part of a line with two end points

    • right triangle -

      A triangle that has a right angle (90°)

    • acute triangle -

      Triangle that has all angles less than 90°

    • obtuse triangle -

      A triangle that has an angle greater than 90°

    • scalene triangle -

      A triangle with all sides of different lengths

    • isosceles triangle -

      A triangle with at least two equal sides and equal opposite angles

    • equilateral triangle -

      A triangle with three equal sides, and three equal angles

    • side -

      A line segment forming part of a polygon (the line on the edge of a shape joining its vertices)

    • angles -

      The amount of turn between two straight lines with a common end point (the vertex)

    • right angle -

      An angle which is equal to 90°, one quarter of a full revolution

    • parallel lines -

      Lines that are always the same distance apart and will never meet

    • intersecting lines -

      Lines that cross over one another at a common point

    • perpendicular lines -

      Lines that intersect and form right angles (90°)

    • transformation -

      Moving a shape to a different position; still has the same size, area, angles and line lengths (flip, turn,or slide)
