Geometry Vocab
| Question | Answer |
|---|---|
| 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 |
