Question
Answer
rectangle   a parallelogram w/ 4 right angles  
ray   a part of a line that starts at one endpoint and extends forever  
complementary angles   two angles whose measures add to 90  
center of rotation   the point about which a figure is rotated  
congruent   having the same size and shape  
correspondence   the relationship between 2 or mre objects that are matched  
equilateral triangle   a triangle w/ 3 congruent sides  
image   a figure resulting from a transformation  
isosceles triangle   a triangle w/ at least 2 congruent sides  
line   a straight path that extends w/o end in opposite directions  
line of symmetry   the imaginary "mirror" in line symmetry  
line symmetry   a figure has line symmetry if one half is a mirror-image of the other half  
obtuse angle   an angle whose measure is greater than 90 but less than 180  
obtuse triangle   a triangle containing one obtuse angle  
parallel lines   lines in a plane that do not intersect  
parallelogram   a quadrilateral w/ 2 pairs of parallel sides  
perpendicular lines   lines that intersect to form right angles  
plane   a flat surface that extends forever  
point   an exact location is space  
polygon   a closed plane figure formed by 3 or more line segments that intersect only at their endpoints (vertices)  
vertical angles   a pair of opposite congruent angles formed by intersecting lines  
rhombus   a parallelogram w/ all sides congruent  
right angle   an angle that measures 90  
right triangle   a triangle containing a right angle  
rise   the vertical change when the slope of a line is expressed as the ratio rise over run  
rotation   a transformation in which a figure is turned around a point  
rotational symmetry   a figure has rotational symmetry if it can be rotated less than 360 around a central point and coincide w/ the original figure  
run   the horizontal change when the slope of a line is expressed as the ratio rise over run  
scalene triangle   a triangle w/ no congruent sides  
segment   a part of a line between 2 endpoints  
semiregular tessellation   a tessellation formed w/ 2 or more regular polygons in which every vertex is identical  
slope   a measure of the steepness of a line on a graph, the rise divided by the run  
square   a rectangle w/ 4 congruent sides  
supplementary angles   two angles whose measures have a sum of 180  
tessellation   a repeating pattern of plane figures that completely cover a plane with no gaps or overlaps  
transformation   a change in size or position of a figure  
translation   a movement (slide) of a figure along a straight line  
transversal   a line that intersects two or more lines  
trapezoid   a quadrilateral w/ exactly one pair of parallel lines  
regular tessellation   a tessellation formed by using regular polygons  
regular polygon   a polygon w/ congruent sides and angles  
angle   a figure formed by 2 rays w/ a common endpoint called the vertex  
acute triangle   a triangle w/ angles measuring less than 90  
acute angle   an angle that measures less than 90  
reflection   a transformation of a figure that flips the figure across a line  
Triangle Sun Theorem   the theorem that states that the measures of the angles in a triangle add up to 180
