Exterior Angles of a Polygon. At each vertex of a polygon, an exterior angle may be formed by extending one side of the polygon so that the interior and exterior angles at that vertex are supplementary (add up to 180). In the picture below, angles a, b c and d are exterior and the sum of their degree measures is 360.
obtuse angle: An angle whose measure is greater than 90 degrees: right angle: An angle of 90 degrees: same side exterior angles: Angles located outside a set of parallel lines and on the same side of the transversal: same side interior angles: Angles located inside a set of parallel lines and on the same side of the transversal: vertical angles

If the sum of the interior angles ... Justify your answer. 22. Y 23. 24. w° 110° z ... You can’t use the Triangle Exterior Angle Theorem with the given ...
Since angles A and B already add up to 120 degrees, this leaves 60 degrees for angle C. Using algebra, this can be represented by: A + B + C = 180 40 + 80 + C = 180 120 + C = 180 C = 60. So this conjecture tells us that if we know two of the angles in a triangle, then we can find the third angle quite simply.
Shock is generally classified into three categories, cardiogenic, circulatory, and distributive. In this chapter we look at these three different types of shock along with the fluid, electrolyte, and acid-base imbalances and nursing implications of all shock states.

The unit of measurement is degree. There are different types of angle like acute angle, obtuse angle, straight angle, right angle and reflex angle. Interior and Exterior angles. The interior points or the parts that lie inside the angle are called interior angles and the part or the point that lies outside the angle is called exterior angle.
Each interior angle of an n-sided regular polygon is 180° − 360° ÷ n. All Polygons. The sum of the exterior angles of any polygon is 360°. The sum of the interior angles of an n-sided polygon is (180 n − 360)°. Interactive animation showing why exterior angles add up to 360° Other angle theorems. Circle theorems. More angle activities
