Concept explainers
a.
To explain about the two pairs of vertical
a.
Answer to Problem 10STP
Vertical angles are always equal
Explanation of Solution
Given information:
Two lines intersect in a plane
if two lines are crossing each other in a plane
Then its vertical angles are always equal to each other
This property is called vertical angle property
b.
To explain about the adjacent angles formed
b.
Answer to Problem 10STP
Adjacent angles are supplementary
Explanation of Solution
Given information: Two lines intersect in a plane
if two lines are crossing each other in a plane Two angles are said to be adjacent when they share common vertex and side
Therefore, adjacent angles are supplementary
