Step-by-step explanation:

OCB=CBO(base angle of isosceles triangle are equal)

now,

OCB+CBO+BOC=180°(sum of angles of triangles)

BOC=180-62

BOC=118°

again,

x=BOC/2{inscribed angle is half of central angle standing on Same base}

x=118/2

x=59°

In a reflection, pairs of corresponding points lie on parallel lines.<br> True or False?
Lerok [7]

The statement that: pairs of corresponding points lie on parallel lines in a reflection, is false.

<h3>What are reflections?</h3>

When a point is reflected, then the point is flipped across a point or line of reflection

When a point is reflected, the following highlights are possible

  • The corresponding points can line on the same line
  • The corresponding points can line on parallel lines

Using the above highlights, we can conclude that the statement is false.

This is so because, corresponding points are not always on parallel lines
