Can you duplicate any angle measure?
It is possible to draw an angle twice the size of a given angle by using a compass and a straightedge. First, draw a ray, creating the vertex of the new angle. Then, using the compass, swing an arc through the original angle, and then swing that same arc, holding the end of the compass at one endpoint of the ray.
What does it mean to duplicate an angle?
The basic idea behind copying a given angle is to use your compass to sort of measure how wide the angle is open; then you create another angle with the same amount of opening.
What is the first step in copying an angle?
Step 1: Draw a ray and call the endpoint B. Step 2: Now go back to the angle you are copying.
Which is twice of given angle?
The measure of an angle is twice the measure of its supplementary angle.
How do you solve supplementary angles?
We can calculate supplementary angles by subtracting the given one angle from 180 degrees. To find the other angle, use the following formula: ∠x = 180° – ∠y or ∠y = 180° – ∠x where ∠x or ∠y is the given angle.
What is the correct order of steps for copying angle ABC?
What is the correct order of steps for copying angle ABC? Create point H at the intersection of the arcs created from point D, and draw a ray from point D through point H. Draw a ray with the endpoint D, and place the compass on point B.
What is the correct order of steps for copying angle ABC quizlet?
When twice an angle is added to 45?
x + (2x + 45) = 180 degrees.
What is the second step in copying an angle?
What is the supplement of ∠ G 37?
The supplement of 37° is 143°. Think of the letter “S” for “Straight line” to remember that supplementary angles add up to 180°.
What is the supplement of an angle?
Two angles are called supplementary when their measures add up to 180 degrees.
