Introduction to Geometry

_________________________ is the branch of mathematics concerned with the properties of shapes, sizes, angles, and dimensions of objects, and the relationships these objects have with each other.

• Algebra
• Calculus
• Geometry
• Trigonometry

A _________________________is a number that describes some characteristic of an object.

• Variable
• Measure

• Function
• Method

If two objects have the same measures but do not necessarily occupy the same space, they are called  _________________________. The symbol for this relationship is  ≅  .

• Congruent
• Similar
• Equal
• Identical

A _________________________ is a specific location in space. It is the only zero-dimensional object.

• Point
• Line
• Circle
• Square

A _________________________ is an unbounded set of points such that the points on the shortest path between any two points in the set consists of points that are also in the set (assuming that path is free to leave the set.)

• Line
• Circle
• Line Segment

• Ray

A line  _________________________  is a completely bounded subset of a line between two boundary points.

• segment
• ray
• slice

• program

What is the name for the measure of a line segment?

• Area
• Volume
• Length
• Weight

A/an_________________________ is a partially bounded subset of a line. It has one boundary point and is unbounded in the other direction.

• Line Segment
• Ray
• Point
• Plane

A/an _________________________  is an object formed by the intersection of two lines or line subsets.

• angle
• circle
• triangle
• square

When all angles formed by an intersection are congruent, those angles are called _________________________  angles.

• Acute
• Obtuse
• Right
• Vertical
