Which line of reflection will map the trapezoid onto itself?

line y = 1.5
line symmetry; the reflection in the line y = 1.5 maps the trapezoid onto itself.

What is the equation for the line of reflection?

The line of reflection is usually given in the form y = m x + b y = mx + b y=mx+by, equals, m, x, plus, b.

What reflections map the figure onto itself?

In order for the figure to map onto itself, the line of reflection must go through the center point. Two lines of reflection go through the sides of the figure. Two lines of reflection go through the vertices of the figure. Thus, there are four possible lines that go through the center and are lines of reflections.

Which figure always has exactly four lines of reflection that map the figure onto itself?

square
A square is an example of a shape with reflection symmetry. In a square, all sides are congruent and each angle is a right angle. There are four lines of reflection that carry the square onto itself. These lines of reflection will always be the lines of symmetry.

What is a reflection line?

A reflecting line is a perpendicular bisector. When a figure is reflected, the reflecting line is the perpendicular bisector of all segments that connect pre-image points to their corresponding image points.

What is the formula for reflection over the y axis?

The rule for a reflection over the y -axis is (x,y)→(−x,y) .

What does onto itself mean?

2 intr to make contact with; communicate with. 3 intr to become aware of (something illicit or secret)

How many reflection symmetries does a regular n gon have?

It is clear that there are always 2n symmetries for any regular n-gon, with half of them being rotations and the other half being their reflections. Therefore for an n-gon with an even number of sides, every nontrivial symmetry in Dn, we shall call it, is either a reflection or rotation.

How many lines of reflection does a regular Pentagon have?

5 lines
A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.
