The main difference between a square and a rhombus is that a square has all its angles equal to 90 degrees and a rhombus does not. A square has 4 lines of symmetry while rhombus only has 2. The diagonal lengths of a square are of the same measure. Rhombus diagonal lengths are of different measures. They are both a quadrilateral, all sides are equal in length, and opposite sides are parallel to each other.
A rectangle has 2 pairs of parallel lines of different lengths but a square has 2 pairs of parallel lines of equal lengths
A trapezoid has a pair of opposite parallel lines of different lengths A square has 2 pairs of opposite parallel lines of equal lengths A triangle has no parallel lines
No but it does have 3 sides 2 of which are of equal lengths.
diagol lines a slanted linesA diagonal line is a lines which is a slanted line
They have equal slopes, equal y-intercepts, equal x-intercepts,and if they are line segments, then they have equal lengths.
A heptagon has 4 diagonal lines and 7 sides and it has 2 congruent diagonal lines and 2 congruent triangles
They are straight lines. The sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side. But subject to that constraint, the sides can have any lengths.They are straight lines.

None are guaranteed.If it is a regular decagon (convex, with all side lengths equal and all angle measures equal), then there are 10 lines of symmetry.
I assume you are wondering are all lengths equal? Yes
