Webm ∠ BFD = 90° (130° − 40° = 90°), so ∠ BFD is a right angle. (b) m ∠ AFE = 180 °, so ∠ AFE is a straight angle. (c) m ∠ BFC = 40° (130° − 90° = 40°), so ∠ BFC is an acute angle. (d) m ∠ DFA = 140° ( 180 ° − 40° = 140°), so ∠ DFA is an obtuse angle. Previous Next Special Angles WebThe measure of a circumscribed angle is equal to 180 degrees minus the measure of the central angle that intercepts the same arc (imagine the center of the circle is point A, the top point is point C and the bottom point is point D, there is a line connecting point A to point C and point D to point A; measurement of angle CXD = 180 degrees - measurement of angle …
