HELP!!

Mathematics
1 answer:
MrRa [10]3 years ago
3 0

Answer:

the correct option is B

Step-by-step explanation:

AC and AB are both radii of circle A

an equilateral triangle is one with all three sides the same length and angle.

from point A of circle A, a compass is use to bisect.

it works because the compasss width is not changed between drawing each side, guaranteeing they are all equal with the same length

using an object and a circular base

1 . Use any cylindrical object with a circular base, each side of the equilateral triangle will be as long as the radius (half the diameter) of the circular object.

2. Draw the first side. It should be exactly as long as the radius of the circular object – the distance halfway across. Make sure that it is perfectly straight!  

If you have a ruler: simply measure the diameter of the object and draw a line that is half as long.

If you don't have a ruler: place the circular object onto a sheet of paper, then carefully trace the circumference with your pencil. Remove the object, and you should have a perfect circle. Use a straight edge to draw a line across the exact center of the circle: the point that is completely equidistant from any point around the circumference of the circle.

3. Trace another arc. Now, shift the circular object so that the edge touches the other end of the line segment. Make sure that the line segment runs through the exact center of the circle. Draw another quarter-arc that crosses the first arc at a point directly above the line segment. This point is the apex of your triangle.

4. Complete the triangle. Draw the remaining sides of the triangle: two more straight lines will connect the apex with the two open ends of the line segment.

The radius of a circle is 6 inches. What is the circle's circumference?<br> Use 3.14 for ​.
Vikentia [17]

Answer:

37.68 inches

Step-by-step explanation:

The equation for the circumference of the circle is:

C=2\pi r

We can substitute 6 in for "r" and 3.14 for "π":

C=2(3.14)(6\ in)\\C=12\ in(3.14)\\C=37.68\ in^

Happy New Year from MrBillDoesMath!

Answer:

Proof by ASA congruence postulate. See below

Discussion:

  Fact 1 :     angle A = angle T             (given)

  Fact 2:    The angles on both sides of point X are equal as vertical angles

                 are equal.

From these facts it follows that angle M = angle H (as all plane triangles have 180 degrees). Also  AM = TH  (given) so

   In the left triangle                          In the right triangle

  (angle M, side AM, angle A)  =      (angle H, side TH, angle T)


Hence the triangles have two congruent angles, and congruent sides included between the angles, so they are congruent by  ASA.


Thank you,

MrB
