Are all rectangles trapezoids?
NO rectangles are trapezoids
Do irregular octagons have lines of symmetry?
They may have no lines of symmetry or they may have some - it all depends upon the shape of the irregular octagon. Only regular octagons have 8 lines of symmetry.
Show three lines of symmetry?
If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.
How many lines of symmetry does a dodecagon?
A dodecagon has 12 sides, and the number of lines of symmetry it possesses depends on the specific characteristics of the shape. A regular dodecagon, where all sides and angles are equal, has 12 lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. Irregular dodecagons may have fewer lines of symmetry, determined by their unique properties.
Does a triangle have more than 1 line of symmetry?
Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.
How many lines of symmetry do all nonsquare rectangles have?
4
Which has more lines of symmetry a square or an rectangle?
All squares are rectangle, but not all rectangles are square. The expected answer is "a square" ... A square has 4 lines of symmetry. A rectangle that is not a square has 2 lines of symmetry. However, the question is ambiguous. Since a square is a rectangle you can say that some rectangles have 4 lines of symmetry. A better question is, "Which has more lines of symmetry; a square, or a rectangle that is not a square?"
What is the counterexample for all parallelograms are rectangles?
any parallelogram that does not have right angles.
How many axes of symmetry has a rectangle?
All rectangles have 2 axes of symmetry, which are the lines joined by the two pairs of midpoints of opposite sides.
Why Can all rectangles be cut in half vertically or horizontally to make to congruent rectangles?
They make two congruent rectangles, not to rectangles! This is because the line joining the midpoints of opposite sides are lines of [reflective] symmetry.
What different shapes have 2 lines of symmetry?
The only known shapes with two lines of symmetry are rhombus and rectangles. These shapes are found by the test of line of symmetry of certain shapes.Sketch a rectangle, which has two pair of congruent and parallel lines and all right angles. Indicate the lines of symmetry. They should pass through each opposite midpoint of the segments of the rectangles.Sketch a rhombus, the shape that has all congruent sides, but have two pairs of congruent angles, which are different from another. Indicate the lines of symmetry. They should pass through both opposite vertices of the rhombus.
Do all shapes have lines of symmetry?
not all shapes have lines of symmetry. one example is a triangle.
Do all octogons have the same number of lines of symmetry?
All regular octagons have the same number of lines of symmetry, but octagons with unequal sides would have fewer lines of symmetry.
What shapes have 4 line's of symmetry?
The square is the only one I can think of. The lines are vertical, horizontal, and both diagonals.
Are all quadrilaterals symmetrical?
Not all 4 sided quadrilaterals have lines of symmetry although some of them do have lines of symmetry.
Do all rectangles have parellel lines?
Yes!
Do all triangles have three lines of symmetry?
no, only equilateral triangles have 3 lines of symmetry
