Identify all the lines of symmetry of the following rectangle.
ladessa [460]

The triangle presented in the image has 2 axes of symmetry because it is only possible to divide it 2 times.

<h3>What are axes of symmetry?</h3>

The axes of symmetry are a concept of geometry that are classified into two groups:

  • The plane axis of symmetry: This is an imaginary line that divides a figure into two parts, ensuring that the symmetrical points are at the same distance from it.
  • The axis of axial symmetry: This is the symmetry around an axis, it is a point of translation and rotation in which all the semi-planes taken from a certain perpendicular bisector have identical characteristics.

According to the above, it can be inferred that the rectangle presented in the image has only two axes of symmetry.

Misha Larkins [42]

Answer:

Answer is reflection across line. When transformation maps X"Y"Z" .Then first transformation for this composition is , and the second transformation is 90° rotation about point X'.

Step-by-step explanation:

When you transform a point across a line y=x then x-coordinate and y-coordinate changes.

Similarly when you reflect a point across the line y=-x then signs are changed and both coordinate change places.

It is the first transformation across the line.
