PLTW IED Constraints Test

constrains two objects so they lie perpendicular

• parallel

• equal

• perpendicular

• colinear

constrains two or more arcs, circles, or ellipses to the same center point

• tangent

• circle

• size

• concentric

constrains two or more objects to create a smooth, continuous curvature between them

• tangent

• smooth/curvature

• concentric

• coincedent

constrains two objects so they share a line

• coincedent

• colinear

• concentric

• symmetry

constrains two lines so they extend in the same direction and never intersect

• equal

• midpoint

• tangent

• parallel

constrains a circle and another object so they touch at the same point

• coincident

• colinear

• tangent

• midpoint

constraint that sets objects to same size

• equal

• colinear

• coplanar

• midpoint

constrains the position of two points or a point and a line or a curve together

• concentric

• colinear

• coincedent

• symmetry

constrains a single line or two pints to lie on the vertical or horizontal axis, whichever is closer

• symmetry

• colinear

• horizontal/vertical

• tangent

constrains two objects so they are identical to each other in relation to a common axis

• midpoint

• symmetry

• equal

• concentric
