Takeout angle -- The angle cut out of a piece of paper so that the paper can be rolled into a right circular cone.
Tangent Line -- a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
Tangent Function -- the trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right triangle.
Tessellate -- To cover a plane with identically shaped pieces which do not overlap or leave blank spaces.
Tetrahedron -- A polyhedron with four triangular faces, or a pyramid with a triangular base.
Torus -- A doughnut shape.
Transformations -- Operations that alter the form of a figure.
Transversal -- A line that cuts across a set of lines or the sides of a plane figure.
Trapezium -- A quadrilateral with no parallel sides.
Trapezoid -- A quadrilateral which has a pair of opposite sides which are parallel.
Triangle -- A polygon with three sides.
Trigonometry -- The study of triangles, with emphasis on calculations involving the lengths of sides and the measures of angles.
Truncated Cone -- A cone or pyramid which has its apex cut off by an intersecting plane.
Theorem -- a rule expressed by symbols or formulas.
Tau -- the ratio constant of a circle's circumference to its radius.
Theta -- A plane angle.
Two-dimensional -- The property of a plane that indicates that motion can take place in two perpendicular directions.
Three-dimensional -- The property of the space in which we live and move that indicates motion can take place in three mutually perpendicular directions.
Translation -- A transformation in which a geometric figure is picked up and moved to another location without any change in size or orientation.
Tan^-1 -- The inverse function of tangent.

Inverse
It is a sequence of numbers such that the ratio of successive terms is a constant.
Umm, X intercept?
Before beginning an apartment search you should know what you're looking for in terms of size, price and neighborhood. You should also know your credit score.
A score is equal to 20.
No, it is not. Grade can be a verb with distinct meanings (to score, to level) or a noun with the same general concept (a score, a level or level rise). It can be a noun adjunct in terms such as grade crossing.
An acute angle is one which in geometrical terms measures between 0 and 90 degrees.
