Are two adjacent angles whose exterior sides are opposite rays always complementary?

No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?

Is An interior angle of a triangle and one of its adjacent exterior angles supplementary?
always
Are adjacent angles sometimes always or never complementary?
Sometimes, because they both have two angles.
The opposite angles of a quadrilateral in a circumscribed circle are always complementary?
false
What is the measure of each exterior angle of a triangle?
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
Are the hypotenuse of a right triangle adjacent to the right angle?
First: there can only be one hypotenuse in a right angled triangle and it is always OPPOSITE the right angle, NEVER adjacent.
Are complementary angles always adjacent?
Are complementary angles alwys adjacent?
Is An interior angle of a triangle and one of its adjacent exterior angles supplementary?
always
Are adjacent angles sometimes always or never complementary?
Sometimes, because they both have two angles.
An interior angle of any polygon and its adjacent exterior angle are always?
equal to 180°
The opposite angles of a quadrilateral in a circumscribed circle are always complementary?
false
What is the formula for sine function?
In a right triangle, its Opposite/Hypotenuse I always use: Soh (sin, opposite/hypotenuse) Cah (cosine, adjacent/hypotenuse) Toa (tangent, opposite/adjacent) Hope this helped! :)

Are the hypotenuse of a right triangle adjacent to the right angle?
First: there can only be one hypotenuse in a right angled triangle and it is always OPPOSITE the right angle, NEVER adjacent.
What is the same about a parrallelogram and a rectangle?
-- four sides -- four angles -- opposite sides are equal -- opposite sides are parallel -- opposite angles are equal -- adjacent angles are supplementary -- sum of interior angles is 360 degrees -- sum of exterior angles is 360 degrees -- area = (length of the base) x (height) -- can always be formed with two triangles -- diagonals bisect each other
Are the adjacent sides of a rhombus blank congruent never sometimes always?
The adjacent sidesof a rhombus are always congruent... that's one of the identifying factors. A rhombus has all sides congruent, opposite sides parallel, and bisecting diagonals.
How do you explain tangent in geometry?
You can explain it either using Sin or Cosine, or you could always just say tangent= opposite/ adjacent
Why are the sine and cosine of an angle always less than 1?
Since the hypotenuse (denominator) is always greater than the opposite or adjacent side (numerator), the ratio will always be smaller than one.
