What are a score or more geometrical terms beginning with T and their meanings?

Answer 1

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.
