# What is a 40 degree angle called?

## What is a 40 degree angle called?

Acute Angle: An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles.

How do you measure a 40 angle?

Step 1: Draw a line segment PQ, match the center of the protractor with O. Check the inner side of the protractor, at angle 40°, mark the point as A. Join OA, the smaller angle AOQ measures the 40° angle. Step 2: The larger angle AOP is the supplementary angle of the angle 40°.

Is 40 degrees a obtuse angle?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

### What is the supplementary of 40 degree angle?

140 degrees
Supplementary of 40 degrees = 180−40=140 degrees.

What kind of angle is ABC?

Angle ABC is a straight angle, or 180°.

How do you measure a 40 degree angle without a protractor?

Set the short end of your ruler flush against the adjacent side of the triangle. Measure the length of the vertical line from the point where it meets the adjacent side to the point where it meets the upper ray of the angle (the hypotenuse of your triangle).

## How do you draw a 40 angle with a protractor?

Steps of Construction:

1. Draw ∠BAC=40o using protractor. By taking A as centre draw an arc which cuts AB and AC at P and Q.
2. Now take O as centre on another line segment EF and taking the same radius PQ draw an arc which cuts OF at R.
3. Join O to S which is the required ∠ROS=40o.

What are the 3 angles called?

Name of Triangle Description
Acute Triangle A triangle with 3 acute angles (3 angles measuring between 0° and 90°).
Obtuse Triangle A triangle with 1 obtuse angle (1 angle measuring between 90° and 180°).

How do you construct a 40 degree angle?

Bisecting an angle

• Copy an angle
• Construct a 30° angle
• Construct a 45° angle
• Construct a 60° angle
• Construct a 90° angle (right angle)
• Sum of n angles
• Difference of two angles
• Supplementary angle
• Complementary angle
• ### How to make 40 degree angle with compass?

First we draw angle of 90 degrees using protractor.

• Now with compass draw an arc of particular length with center as the intersection of two rays of 90 degree angle cutting both the rays at two points A and
• Now without disturbing the compass (i.e using same arc lengths previously drawn) draw two arc from points A and B respectively.
• What is the GCF for 40 and 48?

Find the prime factors of the first number 40. 2,2,2,5

• Find the prime factors of the second number 48. 2,2,2,2,3
• Multiply of all the common prime factors is the GCF value. Which is,8
• What is the complement of a 40 angle?

What is the Complementary Angle of a 40 Degrees Angle? The complement of an angle is obtained by subtracting it from 90 degrees. Thus, the complement of 40° is 90° – 50° = 40°. How do you Find the Value of x in Complementary Angles?
