Question

In exercise 15-18 use the figure. What is a linear pare?

a) A linear pair consists of two adjacent angles formed by intersecting lines, and their measures add up to 180 degrees.
b) A linear pair consists of two opposite angles formed by intersecting lines, and their measures are equal.
c) A linear pair consists of two parallel lines intersected by a transversal line, forming congruent angles.
d) A linear pair consists of two complementary angles formed by intersecting lines, and their measures add up to 90 degrees.

Answer 1

A linear pair consists of two adjacent angles formed by intersecting lines, and their measures add up to 180 degrees.

Step-by-step explanation:

A linear pair consists of two adjacent angles formed by intersecting lines, and their measures add up to 180 degrees. This means that the two angles are supplementary. For example, if one angle measures 60 degrees, the other angle will measure 120 degrees.
