Without measuring, sketch each angle. Then use a protractor to check your accuracy.
angle
Short Answer
The angle without measuring is
With protractor angle will be near about .
Step by step solution
- Apply the protractor postulate
in a given plane is considered.
Any point O between A and H is chosen.
Consider and and all these rays are drawn from O on one side ofrole="math" localid="1648992710364" .
These rays鈥� results in pairing with the real numbers from 0 to 180 in such a way that:
The line role="math" localid="1648992759940" is paired with 0, and with 180.
If is paired with , and with , then role="math" localid="1648992876830" .
– Sketch angle without measuring
Thus, the figure is shown below, have .
– Superimpose the protractor to check the accuracy
By taking a protractor and put it over the . Superimpose the protractor鈥檚 line with the drawn angles line. Measure the angle by using the protractor postulate. The angle will be near about .
