- 1parallel linesParallel lines are always the same distance apart, and will never touch.
- 2perpendicular linesPerpendicular lines meet or cross to form right (90 degree) angles.
- 3straight angleA straight angle is a straight line. It measures 180 degrees.
- 4acute angleAn acute angle measures less than a right angle (less than 90 degrees).
- 5obtuse angleAn obtuse angles measures more than 90 degrees, but less than 180 degrees.
- 6right angleA right angle measures exactly 90 degrees. A right angle forms a square corner.
- 7triangleA triangle is a polygon with exactly three sides and three angles.
- 8acute triangleAn acute triangle is a triangle whose three angles are ALL acute angles (less than 90 degrees).
- 9obtuse triangleA triangle with exactly ONE obtuse angle. (More than one obtuse angle would mean the three angles could not add up to 180 degrees.)
- 10right triangleA triangle with exactly ONE right angle. (More than one right angle would mean the three angles could not add up to 180 degrees.)
- 11equilateral triangleA triangle whose three sides are ALL the same length. (Also called an equiangular triangle, because the three angles would also have equal measures.)
- 12isosceles triangleA triangle with two (or three) sides being equal in length.
- 13scalene triangleA triangle whose three sides all have different lengths.
- 14quadrilateralA polygon having exactly four sides and four angles.
- 15parallelogramA quadrilateral whose opposite sides are both congruent (equal in length) and parallel. Rectangles, squares, and rhombuses (rhombi) are all special types of parallelograms.
- 16rectangleA parallelogram whose four angles are all right angles.
- 17rhombusA parallelogram whose four sides are all congruent.
- 18squareA parallelogram whose four sides are all congruent (making it also a rhombus) and whose four angles are all right angles (making it a rectangle).
- 19trapezoidA quadrilateral with EXACTLY ONE pair of parallel sides - the other pair is NOT parallel, so a trapezoid is not a parallelogram.
- 20pentagonA polygon with 5 sides and 5 angles.
- 21hexagonA polygon with 6 sides and 6 angles.
- 22LineA line is a set of continuous points.
