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.
b & c
Yes opposite angles are equal
Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp. *Remember that alternate interior angles are congruent. To break it down in a better understanding way. 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. If the shape is a parallelogram then you can find the slope of its sides. if they are parallel to each other then it is a parallelogram. 2.) opposite sides of a parallelogram are congruent top and bottom sides are congruent. right and left sides are congruent. 3.) diagonals bisect each other When you draw a straight line from the top right corner to the bottom left corner and from the top left corner to the bottom right corner, the bisect each other or in better terms, the lines cut each other equaly in half. 4.)opposite angles are congruent just as the sides. 5.) consecutive angles are supp. These angels produce a line. this line like all lines will add up to 180 degrees. *Remember that alternate interior angles are congruent.
Yes, they all are congruent and have 4 lines of symmetry
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! :)
A parallelogram has two pairs of opposite congruent lines
O par ell lines and no 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
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
