Question

1. from the figure to the left:

∠f & ∠h are?
supplementary
a linear pair
vertical angles
adjacent angles

Explanation:

• Supplementary angles: Two angles are supplementary if their sum is \(180^{\circ}\). There is no indication that \(\angle f+\angle h = 180^{\circ}\) from the given figure.
• Linear pair: A linear pair is a pair of adjacent angles whose non - common sides are opposite rays. \(\angle f\) and \(\angle h\) do not form such a pair.
• Vertical angles: Vertical angles are formed when two lines intersect. \(\angle f\) and \(\angle h\) are not formed by the intersection of two lines in the required way.
• Adjacent angles: Adjacent angles have a common vertex and a common side. \(\angle f\) and \(\angle h\) share a common vertex \(S\) and a common side.

Answer:

Adjacent angles
