Question

The ray GJ is the angle bisector of ZFGH and m_FGH = 30°. Enter m ZFGJ.The measure of ZFGJ is

Answer 1

Let's recall that an angle bisector divides into two equal parts or angles any angle.

Example: We have an angle of 88 degrees.

The angle bisector divides this angle into two equal parts of 44 degrees.

Now, if the measure of the angle FGH is 30 degrees, what would be the measure of one of the equal parts (angle FGJ) divided by ray GJ?
