How to work out an obtuse angle
Did you know?
WebFirst, drop a perpendicular line AD from A down to the base BC of the triangle. The foot D of this perpendicular will lie on the edge BC of the triangle when both angles B and C are acute. But if angle B is obtuse, then the foot D will lie on BC extended in the direction of B. WebThe sine of an obtuse angle is defined to be the sine of its supplement. For example, sin 120° = sin 60° = 2 . ( Topic 4 .) To see why we make this definition, let ABC be an obtuse angle, and draw CD perpendicular to AB extended. Then we define the sine of angle ABC as follows: sin ABC = CD CB .
WebOne simple way of doing this is, Given the 3 coordinates, find out the lengths of the 3 sides (X,Y,Z)of the triangle by the standard formula length=√ ( (x2-x1)^2+ (y2-y1)^2) Now provided the triangle exists, take the 2 shortest sides. Let us assume they are X and Y . Now if Z^2 > (X^2+ Y^2) then the triangle is obtuse.

We first add the 4 known angles: 120° + 100 + 100 + 110° = 430°. We then subtract this from 540°: 540 – 430 = 110 and so the missing angle is 110°. Angles in a pentagon always add up to 540°. Angles in a pentagon always add to 540°.
