complementary angles are defined as 90 degrees - the given angle so 90-80=10 10 degree angle is complementary to an 80 degree angle
A rhombus, trapezoid or parallelogram could all contain a 45 degree vertex. Squares and rectangles only have 90 degree vertices.
vertex angle
the vertex of the angle is the point
The vertex angle is connected to the vertex point
The supplement of an 80 degree angle is an 100 degree angle.
180-100=80 degree angle
a 10-degree angle
The compliment of a 100 degree angle is a 80 degree angle.
80 degrees
complementary angles are defined as 90 degrees - the given angle so 90-80=10 10 degree angle is complementary to an 80 degree angle
It is a straight line which passes through the vertex of the angle and divides it into halves.
A rhombus, trapezoid or parallelogram could all contain a 45 degree vertex. Squares and rectangles only have 90 degree vertices.
An 80 degree angle is an acute angle. Any angle measurement that falls below 90 is acute while anything above is obtuse.
80 degrees.
