A constraint that forces two selected lines to meet at a right angle is ___________.

• parallel

• vertical

• perpendicular

• coincident

Constrains two curves or a line and a curve at one point without overlapping.

• equal

• smooth

• tangent

• symmetry

Constrains two points together or one point to a curve.

• coincident

• colinear

• concentric

• parallel

Used to assign the same size to similar geometric entities; lines with the same length or circles with the same radius/diameter.

• horizontal

• equal

• vertical

• parallel

A constraint that causes a line to be drawn parallel to the y-axis.

• horizontal

• vertical

• parallel

• datum

A constraint that causes 2 or more lines to be equal distance from each other.

• Parallel

• Perpendicular

• Equal

• Coincident

A constraint that causes the centers of two arcs, circles, or ellipses have the same location.

• Vertical

• Horizontal

• Concentric

• Collinear

A constraint that causes two lines to lie on the same plane.

• Coincident

• Collinear

• Concentric

• Perpendicular

A constraint that causes lines to be drawn parallel to the x-axis.

• Linear

• Nonlinear

• Vertical

• Horizontal

A constraint that causes selected geometric entities to become mirror images constrained about a selected line or axis.

• Symmetry

• Concentric

• Equal

• Parallel
