Parallel lines with no transversal:Lines that are equidistant and never meet

Cylinder:a solid object with two identical flat circular or elliptical ends and one curved

side.

Equilateral Triangle:

A triangle with all three sides of equal length

Two perpendicular, bisecting line segments:two lines that meet at a 90 degree angle to divide two lines equally

Vertical angles formed by two intersecting lines:

angles opposite each other when two lines cross

Circle with 4-6 measurable diameters:a circle that is divided into 4 – 6 equal parts

Isosceles trapezoid:a quadrilateral containing parallel lines and two equal sides

Quadrilateral that's equiangular but not equilateral:a 4 sided object that contains angles of the same measurement but unequal

sides

Reflective Symmetry :A type of symmetry where one half is the reflection of the other half

Octagon:an eight sided figure

Rotation of 3-D Object:central point that stays fixed and everything else moves around that point in a

circle
