Find lengths and measures of bisected lines and angles

A line segment is bisected, forming two new line segments. If the original line segment had a measure of 78 inches, what is the measure of each new line segment?

Bisecting a line segment means dividing it into two congruent line segments.
The original line segment measures 78 inches. Divide by 2 to find each new, smaller line segment.

78 ÷ 2 = 39

So, each new line segment measures 39 inches.

After bisecting an angle measuring 90°, Robert has two angles. What is the measure of each new angle?

Bisecting an angle means dividing it into two congruent angles.
The original angle measures 90°. Divide by 2 to find each new, smaller angle.

90° ÷ 2 = 45°

So, each new angle measures 45°.
