Geometry Vocab

scale drawing a proportional drawing of a life sized object
scale factor the ratio of any two corresponding sides in a set of similar figures
angle a figure formed by two rays or arms that share an endpoint or vertex
supplementary angles a pair of adjacent angles whose measurements add up to 180°
complimentary angles a pair of adjacent angles whose measurements add up to 90°
vertical angles a pair of angles that are not adjacent and are formed by two intersecting lines; vertical angles have the same measure and are congruent
adjacent angle a pair of angles that share a common arm and a common vertex; adjacent angles cannot overlap
quadrilateral A polygon with FOUR sides, FOUR angles, and whose interior angles add up to 360 degrees.
construction the drawing of various geometric figures using only a protractor and a straightedge or a ruler
obtuse angle an angle that measures between 91 degrees and 179 degrees
acute angle an angle that measures between 1 degree and 89 degrees
right angle an angle that measures exactly 90 degrees
isosceles triangle A triangle with TWO EQUAL SIDES
scalene triangle A triangle with NO EQUAL SIDES
equilateral triangle A triangle with THREE EQUAL SIDES
circumference the distance around the outside of a circle
radius a line segment that connects the center of a circle to any point on the outside of a circle; the distance halfway across a circle; two radii are equal to one diameter
diameter a line segment that connects two points on a circle and passes through the center of the circle; the distance across a circle; one diameter is equal to two radii
triangle a closed polygon with three sides and three angles and whose interior angles add up to 180°
area the measure of the space inside a flat, 2D shape
prism a three-dimensional solid with flat faces that has at least two congruent, parallel faces called bases
cross section the two-dimensional shape that results from cutting a three-dimensional shape with a plane
surface area the sum of the area of all the surfaces on a three-dimensional solid
net a two-dimensional pattern that forms a three-dimensional solid when folded
volume the amount of space inside a three-dimensional object
circle the set of all points in a plane that are the same distance from a given center point
