25 o because sOme of them are perpendicular
No
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
A square, rhombus and a kite are examples of shapes whose diagonals bisect each other at 90 degrees
The congruent and symmetrical shapes are shapes that have at least a line of symmetry. Some examples:isosceles trianglesequilateral trianglessquaresrectanglesisosceles trapezoidsregular pentagonany regular n-gon shapes!There are many congruent shapes that follow the given conditions!
25 o because sOme of them are perpendicular
H M E W F Z some other i think
Some do, some don't.
none of them. The cube has parallel and perpendicular and os does the cuboid.
There are many geometrical lines and some of them are:- Parallel lines Perpendicular lines Intersecting lines Lines of symmetry Line segments Straight line equations Line of best fit Dotted lines Boundary lines Imaginary lines
No
Some examples are a square, rectangle, that is all I know so far
A kite, if the topmost angle is right and none of the others are.
A line is perpendicular to another if it meets or crosses it at right angles (90°). Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. In the figure above, the line AB is perpendicular to the line DF. If they met at some other angle we would say that AB meets DF 'obliquely'. Move the point A around and create both situations. Move the mouse carefully to get AB exactly perpendicular to DF....

Both lines intersect other lines, but the difference is a perpendicular line intersects another line at a 90 degree angle meanwhile the intersecting lines can meet at any angle
Perpendicular lines = Right Angles, thus any right angle related things work, and you know the angle of one of the 3 (90 degrees) so the perpendicular line as a slope of 90 minus the the angle of the undefined: Since the angles of a triangle must add to 180 Undefined + Perpendicular + Right Angle (90) = 180 Or something like that... been a while since I did geometry... hope this helps * * * * * A line with an undefined slope is a vertical line and so a line that is perpendicular to it is a horizontal line. In the coordinate plane, that would be a line with the equation y = c (for some constant c).
