Question

(g.5b, g.5c) find the complement of ∠jmk. a ∠kml b ∠hmj c ∠gmh d ∠kmj (g.4a) which is another name for line ℓ? f $overrightarrow{ab}$ g c h $overrightarrow{bd}$ j p (g.4a) name the intersection of lines ℓ and m. a a b b c c d p

Step1: Recall complement - angle definition

Two angles are complementary if their sum is 90 degrees.

Step2: Identify the complementary angle

From the protractor, we can see that \(\angle JMK\) and \(\angle KML\) together form a right - angle (90 degrees). So the complement of \(\angle JMK\) is \(\angle KML\).

A line can be named by any two points on the line. Line \(\ell\) contains points \(B\) and \(D\), so another name for line \(\ell\) is \(\overleftrightarrow{BD}\).

The intersection of two lines is the point where they cross. Lines \(\ell\) and \(m\) cross at point \(B\).

Answer:

A. \(\angle KML\)
