# What is the measure of a straight line or straight angle in degrees?

A straight angle is by definition 180°.

### An angle that forms a straight line?

An angle that forms a straight line has an angular measure of 180 degrees.

### An angle with a measure of 180degrees is called a what angle?

An angle with 180 degrees is a straight line, so it's known as a straight angle.

### What does a straight line measure in degrees?

Lines are not measured in degress, however there is a straight angle which measures 180 degrees.

### What does a straight angle makes?

A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees

### What does an obstuse angle measure?

An obtuse angle is any angle which measures between 90 degrees (that is, a right angle), and 180 degrees (that is, a straight line).

### How can you get the measure of an interior angle if you have the measure of the exterior angle of a regular polygon?

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

### What is the measure of an interior angle where the exterior angle measures 18 degrees?

Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line

### There are 90 degrees in a right angle how many degrees in a straight line?

There are no degrees in a straight line. The angle between two line segments that looks like a single straight line if you didn't know where the vertex of the angle is, measures 180 degrees, and is called a "straight angle".

### An angle with a measure equal to 180 degrees?

An angle of 180 degrees has no name, but its subtending lines would form one straight line.

### What is an angle called that measures 180 degrees?

An angle that measures 180 degrees is a straight angle, or straight line. Line.

### Why is a straight angle forms a straight line?

A straight angle is 180 degrees, or twice the measure of a right angle. Therefore, it looks like a right angle that has been folded out into a flat line. Another way is to look at the arch of a 180 degree angle as a semicircle. Connect both ends of the semicircle and you have a straight line.

### How do you find the measure of the exterior angle of a polygon?

180 minus interior angle = exterior angle because there are 180 degrees on a straight line

### What are the angle measurements of a hexagon?

Any particular angle can have any measure you like between 0 and 360 degrees - except 180 degrees which is a straight line.

### What is an angle that measures 180 degrees?

An angle measuring 180 degrees is a straight angle, or straight line.

### A angle has measure of 180?

An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.

### What angle is found on a straight line?

a straight line is also called a straight angle. it is 180 degrees.

### How much degrees is in a straight angle?

A straight angle is exactly 180 degrees. It looks like a straight line.

### A straight angle contains how many degrees?

A straight angle has 180 degrees. It is an angle that has sides in opposite directions from its vertex. A straight angle will look like a straight line.

### What shape has a acute angle a right angle and a straight angle?

An acute angle is an angle less than 90 degrees. A right angle is 90 degrees. A straight angle is a straight line. For example: take a 90 degree angle and straighten it out to form a line, and it becomes a straight angle.

### Which could be the measures of the angles of an obtuse triangle?

The measure can be anywhere from 91 degrees to 179 degrees. 90 degrees is a right angle and 180 degrees is a straight line.

### What is the measure of the angle formed by opposite rays?

180 degrees because opposite rays form a straight line.

### What angle has the greatest measure?

An angle can have up to 180 degree's. A circle can have up to 360 degrees. An angle with 180 degrees is a straight line. If you went any farther than it would change into a 179 degree angle, and so on.

### An irregular quadrilateral has exterior angle measures of 93 85 and 89 what is the measure of the fourth interior angle?

The fourth exterior angle is 93 degrees so the fourth interior angle must be 87 degrees because there are 180 degrees on a straight line.

### What are angles that measure less than 90 degrees?

A right angle is an angle whose measure is exactly 90 degrees. Continuing around the circle, next is the obtuse angle. An obtuse angle is an angle whose measure is in between 90 and 180 degrees. The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees. Thus the name - the two rays form a straight line. A negative angle is also possible. This… Read More

### How many right angles are needed to form a straight angle?

A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.

### A angle that measures 180 degrees?

It is called a straight angle. It is just a straight line.

### What is the measure of the interior angle if its exterior angle is 140 degrees?

40 degress because a straight line is 180 degrees and an interior angle with its exterioir angle is a line spilt in half so to find the interior/exterior angle, taek 180 and subtract the interior/ exterior angle and then you will get the the other angle, sorry this is kinda conufsing!

### Why it makees sense that a straight angle forms a straight line?

If you draw a straight line on a piece of paper and place a protractor over it you will see the reading is 180 degrees. In this sense a straight angle is 180 degrees.

### How can you find out which angle is supplementary?

the angle on a straight line is 180 degrees, the angle of semicircle at centre is 180 degrees

### How are straight angle's different from right angles Is this a statement?

A straight angle is an angle that is 180 degrees exactly (a straight line). A right angle is 90 degrees (like the corners of a square.)
