We know that a straight angle has a measure of 180 degrees. Therefore, using the angle addition postulate: m∠ABC = m∠ABD + m∠DBC. Since ∠ABC is a straight angle: 180 = m∠ABD + m∠DBC. Using the given value of m∠DBC which is 52: 180 = m∠ABD + 52
given ∠ABC is bisected by ray BD. D is interior of angle ∠ABC.

WebABCD is a rhombus with diagonals that intersect at F F. Find the m ∠ A D C m∠ADC, if m ∠ A B D = 2 x + 3 m∠ABD=2x+3 and m ∠ D B C = 4 x − 1 m∠DBC=4x−1. Webthen ∠LEN and ∠NEM are linear pairs. m∠ABD + ∠DBC = 180°, since the measure of ∠ABD and ∠DBC, are equal to 180°, and at the same time they are adjacent angles, then we call them linear pairs. Vertical Angles - non-adjacent angles formed by two interesting lines, and the measures are equal. Examples: There are two lines that ...
