# What is the supplement of a 130 degree angle?

## What is the supplement of a 130 degree angle?

The supplement of 130° is the angle that when added to 130° forms a straight angle (180° ).

## How do you construct a 135 degree angle with a compass?

Draw a line segment AB, take a point P below it. Through P draw a line parallel to AB using ruler and compass only. Draw a line AB and then construct another line parallel to AB which is 4 cm above it. Draw a line AB and then construct another line parallel to AB which is 3 cm below it.

How do you make a 105degree angle with a compass?

1. draw 120 degree angle.
2. then draw 90 degree angle.
3. the angle between the two rays will be 30 degree, draw the angle bisector.
4. now 90 + 15 = 105.

What is the supplement of 140 degree angle?

Examples of Supplementary Angles 140° + 40° = 180°

### What is the sum of the degree measures of the complement and the supplement?

2 Answers. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.

### What field of view is 120?

FOV: 120 degrees Another wide angle camera, 120 degree FOV is again a fit for huddle spaces. At one foot away, you gain 3.4 feet. At ten feet from the camera, that means 34 feet.

What is the FOV of a security camera?

One aspect of setting up a security camera is its field of view (FOV). Webster’s dictionary would tell you that a camera’s field of view is the angle between two rays passing through the perspective center of a camera lens to the two opposite sides of the format.

How do you construct a 135 degree angle and bisect it?

Draw an angle of 135∘ and bisect it. Now draw two arcs that are intersecting each other above point O and join the point to O. Then we will draw the bisector of \$\angle ROA\$ named OD which will make \$\angle DOB = {135^ \circ }\$ . Then draw the bisector of this newly drawn angle.

## What is a 135 degree angle called?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

## How do you construct a 45 degree angle?

A 45 degree angle is the half of 90° angle. For its construction, you first construct a 90-degree angle as discussed above. Then, you bisect this angle. You get two 45 degree angles. Note: For constructing angles like 15 degrees or 22.5 degrees, you further bisect 30 degree angle and 45 degree angle respectively.

How do you construct an angle of 120 degrees?

Let us say, you are asked to construct an angle of 120 degrees. The required steps are: Draw a line segment BC, which is one of the arms of the angle that is to be constructed.

What are the steps for construction of a compass?

The steps for its construction are: Step 1: Draw a line segment. Mark the left end as point O and the right end as point B. Step 2: Take the compass and open it up to a convenient radius. Place its pointer at O and with the pencil-head make an arc which meets the line OB at say, P.

### How to construct a 90 degree angle in AutoCAD?

Construct a right angle 90°. (i) To construct 90° angle, we are going to bisect the straight angle 180°. (ii) Mark a point ‘O’ on a straight line ‘l’. (i) With ‘O’ as center draw arcs of any radius to cut the line l at A and B. (ii) Now ∠AOB = 180°.
