Let's start with the definition. Definition: Line segments are congruent if they have the same length So lines and rays would be congruent if they had the same length. However, Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length. It know it's a LONG story, the the bottom LINE is they have no length so they can't be congruent.
sides (no, not angles, SIDES, as in LINES,) that are the same length and thickness. Just like congruent shapes, but with lines. hope you find lots of congruent lines! :)
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
A heptagon has 4 diagonal lines and 7 sides and it has 2 congruent diagonal lines and 2 congruent triangles
Three vertical parallel lines: |
Yes, they all are congruent and have 4 lines of symmetry

A parallelogram has two pairs of opposite congruent lines
O par ell lines and no congruent lines

No. Angles are not congruent. (Triangles may be congruent.)
Rectangles do not have congruent lines. A square can always be called a rectangle. But a rectangle can't always be a square.
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
Not necessarily.
yes, intersecting lines form two pairs of congruent angles
