An infected first branchial cleft sinus or fistula may cause aural drainage in the absence of otitis media or otitis externa. A child presenting with both a draining ear and a tender mass in the neck may rarely have a first branchial cleft cyst associated with a sinus or fistula tract.
1 What is formed when two complementary angles share one ray? A. the complementary angles form a line with the shared ray B. the complementary angles form a right angle with the shared ray C. the complementary angles form vertical angles with the shared ray D. the complementary angles form an obtuse angle with the shared ray The answer is B right??? Mathematics.
By Deb Russell. Definition: As shown in the image, the two parallel lines are both intersected by another line. The alternate angle 1 and angle 4 will share the same measure of degrees. Likewise angle 2 and angle 3 are alternate angles and share the same measure of degrees. The alternate angles in the image are both interior angles. The same will hold true for exterior angles. Alternate angles are equal. Examples: In geometry, two angles that lie on opposite sides and at opposite ends of a line that goes through two or more lines on the same plane (transversal).
