What is the complement of 70 degrees?

Complementary angles are angles that when added up by their angle, sum up to 90 degree. Here you have 70 degree. To find the complement, just subtract that from 90 degree. So 90 degree – 70 degree = 20 degree.

Is 19 degrees and 71 degrees complementary or supplementary?

The supplementary angle adds to 180. So if the given angle is 19, then the complementary angle is 90-19=71.

What is the complement of 9 degrees?

To determine the complement, subtract the given angle from 90. 90 – 9 = 81° The complement is 81 degree.

What is the complement of 50 degrees?

90-50

What is the complement of 35 degrees?

55

What is the complement of 62 degrees?

28°

What is the complement of 55 degrees?

90 – 55

What 2 angles add up to 90?

Two angles are called complementary when their measures add to 90 degrees.

What are two angles that add up to 360?

When the sum of the measures of two angles is 360°, we call the two angles explementary angles.

What are two angles that add up to 180 degrees?

Supplementary angles are two angles whose sum is equal to 180∘. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.

Where do two rays connect to an angle?

An angle is formed by two rays with a common endpoint. Each ray is called an arm of the angle. The common endpoint is called the vertex of the angle. The measure of an angle is a number representing the spread of the two arms of the angle.

Is a vertex a ray?

A ray is a part of a line that has one endpoint and continues indefinitely in one direction. A vertex is a point of intersection of the lines or rays that form an angle.

How do you write a line segment AB?

We write the name of a line segment with endpoints A and B as “line segment AB” or as . Note how there are no arrow heads on the line over AB such as when we denote a line or a ray.

What does AB with a line over it mean?

Line: A line is a set of points extends in two opposite directions without end. The notation, for example, AB (written with a line symbol <—> over the letters), is read as “line AB” and refers to the line that has points A and B.

What is the end point of ray AB?

An end point is a point used to define a Line Segment or a Ray. A Line Segment has two endpoints while a Ray has one endpoint. A is an endpoint.

What does this symbol mean ⊥?

The up tack or falsum (⊥, /bot in LaTeX, U+22A5 in Unicode) is a constant symbol used to represent: The truth value ‘false’, or a logical constant denoting a proposition in logic that is always false (often called “falsum” or “absurdum”).
