BUILDING BLOCKS OF GEOMETRY

• POINT - an object in geometry that has zero dimension, and is represented by a dot

• LINE - an object that has one dimension, and extends infinitely

• PLANE - an object that has two dimensions, and extends infinitely

Multiple Select

Check off the two kinds of lines that share the same space / cross each other

• Parallel

• Perpendicular

• Intersecting

• Skew

ANGLES

• The intersection of two lines at a point (called a vertex)

• Measured in a unit called degrees

• When measuring, you use a tool called a protractor

Kinds of Angles

• Acute - Less than 90°

• Obtuse - Greater than 90°

• Right - Exactly 90°

• Straight - Exactly 180° (A straight line)

Multiple Choice
