GEOMETRY
acute angle - an angle that measures less than 90 degrees
acute triangle - a triangle with each angle less than 90 degrees
adjacent - next to, side by side
altitude - a line segment that joins a figure's vertex to its opposite side; it is also
perpendicular to the opposite side
angle - two rays that share an endpoint
arc - part of a circle or any curve
area - the amount of surface inside a shape
bisect - to divide into two parts
center - exactly in the middle
chord - a line segment that joines two points on a circle
circle - a figure made up of points the same distance from another point
circumference - the distance around a circle
complementary angle - one of two angles whose sum is 90 degrees
concave - a polygon with an angle greater than 180 degrees
concentric - with the same center
cone - a solid with a circle base and one vertex
congruent - having the same size and shape

GEOMETRY

acute angle - an angle that measures less than 90 degrees acute triangle - a triangle with each angle less than 90 degrees adjacent - next to, side by side altitude - a line segment that joins a figure's vertex to its opposite side; it is also perpendicular to the opposite side angle - two rays that share an endpoint arc - part of a circle or any curve area - the amount of surface inside a shape bisect - to divide into two parts center - exactly in the middle chord - a line segment that joines two points on a circle circle - a figure made up of points the same distance from another point circumference - the distance around a circle complementary angle - one of two angles whose sum is 90 degrees concave - a polygon with an angle greater than 180 degrees concentric - with the same center cone - a solid with a circle base and one vertex congruent - having the same size and shape construct - to draw a geometric figure with a compass and ruler convex - a polygon with each angle less than 180 degrees coordinate grid - a graph for finding points coordinates - numbers or letters that describe a position

cube - a solid with six square faces cylinder - a solid with two circular faces and one curved surface decagon - a polygon with ten sides degree - a unit for measuring angles diagonal - a line joining opposite corners in a shape diameter - a line segment in a circle or sphere; it has endpoints on the circle and goes through the center dimension - a measure of width, length, or height distance - the amount of space between things or places edge - a place where two surfaces of a solid meet endpoint - a point at the end of a line segment, ray, or arc equilateral triangle - a triangle with all sides the same length equivalent - having the same value, worth, or meaning face - a flat surface on a solid horizontal - at a right angle to vertical irregular polygon - a polygon with sides that are two or more different lengths isosceles triangle - a triangle with two equal sides line - a straight object that has no ends or thickness line of symmetry - a line that divides a shape into congruent halves line segment - a part of a line described by its two endpoints obtuse angle - an angle that measures more than 90 degrees and less than 180 degrees obtuse triangle - a triangle with one angle greater than 90 degrees opposite - across from; on the other side

right triangle - a triangle with one 90 degree angle rotate - to turn or to spin, especially around an axis scale - units on the x and y axis scale drawing - a drawing of objects that are proportional to real objects scalene triangle - a triangle with no equal sides sector - a part of a circle formed by two radii and an arc semicirlce - half of a circle slide - to move a shape without turning or flipping it solid - an object that has three dimensions sphere - a solid object that is completely round straight angle - an angle that measures 180 degrees supplementary angle - one of two angles whose sum is 180 degrees surface - the outside of a solid figure symmetry - the property of having two halves that are mirror images tessellation - a pattern of shapes without gaps or overlaps three-dimensional - having points or sides that are not all on one plane transformation - to move a figure in a particular way translate - to slide a figure on a straight line to a new location trapezoid - a quadrilateral with exactly one pair of paralles sides triangle - a polygon with three sides two-dimensional - having length or width but no depth or height vertex - to points where sides or edges meet vertical - perpendicular to the horizon; going straight up or down

volume - the amount a solid holds x-axis - the horizontal line in a coordinate grid x-coordinate - the first number in an ordered pair; the horizontal position of a point y-axis - the vertical line of a coordinate grid y-coordinate - the second number in an ordered pair; the vertical position of a point
