Geometry Terms Crossword

Two lines that cross to create four 90 degree angles
if you add the same number to both sides of an equation, the sides remain equal
subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same
if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
: multiply both sides of an equation by the same number, the sides remain equal
divide both sides of an equation by the same nonzero number, the sides remain equal.
a = b, b = c, then a = c
a = b, then b = a. That is, we can interchange the sides of an equation, and the equation is still a true statement.
multiply a sum by multiplying each addend separately and then add the products.
add or multiply regardless of how the numbers are grouped.
states that order does not matter. Multiplication and addition are commutative.
the middle point on a segment or line
Congruent segments are simply line segments that are equal in length.
: If point B lies in the interior of angle AOC, then. The postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.
given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC
Angle forming at 90 degrees
Congruent segments are simply line segments that are equal in length. Congruent means equal. Congruent line segments are usually indicated by drawing the same amount of little tic lines in the middle of the segments, perpendicular to the segments.
Two angles that add up to 180 degrees
These angles are formed when two lines cross each
: A line that splits an angle in half.
