False
*APEX*
Interior angles are 180 degrees Exterior angles are 360 degrees
Exterior and interior angles at the vertex of a triangle add up to 180 degrees
No.Take a look at this picture...http://www.onemathematicalcat.org/Math/Geometry_obj/graphics/summing_exterior_angles.pngThe exterior angle + the interior angle = 180 degrees180 - the interior angle = the exterior angle
No. 360 degrees is a full circle. These two angles, when added together would form a straight line, or 180 degrees.
Interior angles add up to 3960 degrees Exterior angles add up to 360 degrees
False. apexs
They are all 60 degrees.
Yes
No because they add up to 180 degrees
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
Because it has eight sides it is an octagon so:- Exterior angles: 360 degrees Interior angles: 1080 degrees
They equal the supplement of the interior angle it is adjacent to. (180-int. angle) E.g: the exterior angles of an equilateral triangle are each equal to 120 degrees.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
Yes. Combined, they would form a straight line, or 180 degrees.
No because an exterior angle and an interior angle of a polygon add up to 180 degrees but exterior angles around a polygon add up to 360 degrees
Exterior angle 40 degrees Interior angle 140 degrees
Interior angles are 180 degrees Exterior angles are 360 degrees
