Geometry Vocabulary

What is a Circle?

• all sides congruent and all four right angles.

• a round thing

• the set of points in a plane that are equidistant from a fixed point called the center.

• line that intersects a circle in two points.

What is a Chord?

• segment that connects two points on the circle.

• chord that passes through the center of the circle.

• the set of points in a plane that are equidistant from a fixed point called the center.

• segment whose endpoints are the center of the circle and a point on the circle.

Angle of Elevation is

• a 3-dimensional figure is the number of cubic units contained in the solid.

• The angle that an upward line of sight makes with a horizontal line

  as true.

• a statement or conjecture that can be proven true by given, definitions, postulates, or already

  proven theorems.

• reasoning that uses a number of specific examples to arrive at a plausible

  prediction.

Secant is
