Week of March 19th - March 23rd

Students will classify quadrilaterals using their attributes, draw lines of symmetry, and problem solve using a model. On Wednesday, students will take the Chapter 14 Geometry Cumulative Test. On Thursday and Friday, students will review different skills and concepts taught from the beginning of the year in preparation for the GA Milestones. 



Chapter 14 Vocabulary Words
acute triangle - a triangle that has 3 acute angles
acute angle - angle with a measure that is greater than 0 degrees and less than 90 degrees
degree - unit used to measure an angle
angle - geometric shape formed with two rays share the same endpoint
intersecting - lines that meet or cross each other
endpoint - point at the beginning of the ray or line segment
line of symmetry - fold line indicating that a figure's two halves match exactly
line - straight set of points that extend forever in opposite directions
line symmetry - if a figure can be folded over a line so that one half of the figure matches the other half, it has line symmetry
line segment - part of a line between two endpoints
obtuse triangle - triangle with 1 obtuse angle
obtuse angle - angle that measures greater than 90 degrees but less than 180 degrees
parallel - lines that are always the same distance apart. Parallel lines do not meet.
one-degree angle - an angle that turns 1/360 of a circle
perpendicular - line that meet or cross each other to form right angles
parallelogram - a quadrilateral with opposite sides equal in length and parallel. Opposite angles have the same size. 
ray - part of a line that has one endpoint and goes on forever in one direction without ending
point - exact location represented by a dot
rhombus - quadrilateral with 4 equal sides. Opposite sides are equal in length and parallel
rectangle - quadrilateral with 4 right angles. Both sets of opposite sides are equal in length and parallel
right triangle - triangle with 1 right angle
right angle - angle with a measure of 90 degrees
trapezoid - quadrilateral with exactly one pair of parallel sides
square - quadrilateral with 4 right angles and 4 equal sides. Opposite sides are equal in length and parallel.
