Question

Point C is reflected across AB such that it maps onto point D. Points C and D are then connected to form CD . Which of the following must be true?

(1) CD bisects AB
2)CD is parallel to AB
3) AB =CD
4) CD is perpendicular to AB

Answer 1

Answer:

2)CD is parallel to AB

Answer 2

When a point is reflected, it must be reflected across a line.

The true statement is (4) CD is perpendicular to AB

From the question, we understand:

• Point C maps onto point D
• C is reflected across line AB

The above highlights mean that:

Point C and point D at on the either sides of line AB

So, when they are connected to form a line, line CD will meet line AB at 90 degrees

Hence, the true option is (d)
