How can congruent segments and lengths be created with a tool with no marked measurements?

1 answer:

4 0

STEPS:
1. Using a straightedge, draw a reference line, if one is not provided.
2. Draw a dot on the reference line to mark your starting point for the construction.
3. Place the point of the compass on point A on the given figure.
4. Stretch the compass so that the pencil is exactly on B. Make a small arc through B.
(This small arc will show that you measured the length of the segment with your compass.)
5. Without changing the span of the compass, place the compass point on the starting point (dot) on the reference line and swing the pencil to create an arc crossing the reference line.
6. Label your copy.

No choice on the list is reasonably close to the correct answer.

The question is the same as asking "How much of the whole circle has
black polka-dots in it ?"

The sections of the circle aren't labeled, but we can see that the polka-dot
section is a little more than 1/4 of the circle ... maybe 30% of it ... so the
probability is a little more than 1/4 and close to 30%.

The choices are: A). 50%. ... B). 20%. ... C). 5%. ... D). 56.7%.

Choice B). is the closest, but that's only because the others are even
more absurd. It's not saying much for B).

Answer:

C. The perimeter of ΔABC is 7.6 units.

Step-by-step explanation:

Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.

A. The perimeter of ΔABC is 9.9 units.

B. ΔABC is an equilateral triangle.

C. The perimeter of ΔABC is 7.6 units.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.

The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:

$Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$
