Запиши кількість трикутників на зобра- женні. Визнач групи рівних трикутників і запиши їх назви. Очотирикутник Опрямокутник Dквадрат​

Answer 1

если радиус 32мм значит 64мм это Диаметр

Значит пиши: D=64мм сори если неправильно, я украинский 50% от 100% знаю ;)

Answer 2

To solve this problem, let's break it down step by step.

Step 1: Constructing the Circle and its Diameters

The problem asks us to construct a circle with a radius of 32 mm and two diameters within it.

A circle is a set of points equidistant from a fixed point called the center. The radius is the distance from the center to any point on the circle. In this case, the radius is 32 mm.

To construct the circle, we can use a compass. Place the compass point at the center of the circle and draw an arc with a radius of 32 mm. This arc will intersect the circle at two points, which will be the endpoints of the diameters.

Step 2: Labeling the Intersection Points

The problem asks us to label the points where the diameters intersect the circle with letters. Let's label them as follows: - The first intersection point: A - The second intersection point: B

Step 3: Connecting the Intersection Points

The problem asks us to connect the intersection points (A and B) sequentially. This means we need to draw a line segment from point A to point B.

Step 4: Naming the Resulting Figure

The problem asks us to name the resulting figure. Since we have connected two points on the circle, the resulting figure is a chord.

Step 5: Finding the Perimeter of the Figure

The problem asks us to find the perimeter of the figure. In this case, the figure is a chord, which is a line segment. To find the perimeter, we need to calculate the length of the line segment AB.

To calculate the length of AB, we can use the formula for the circumference of a circle. The circumference of a circle is given by the formula: C = 2πr, where r is the radius. In this case, the radius is 32 mm.

Using the formula, we can calculate the circumference of the circle: C = 2π(32) = 64π mm.

Since AB is a chord, it is a part of the circumference of the circle. The length of AB is equal to the length of the arc it subtends on the circle. In this case, the length of AB is equal to half the circumference of the circle: AB = (1/2)(64π) = 32π mm.

Therefore, the perimeter of the figure is 32π mm.

Step 6: Counting the Triangles in the Figure

The problem asks us to count the number of triangles in the figure. From the given information, we can see that there is only one triangle in the figure. Therefore, the number of triangles in the figure is 1.

Step 7: Identifying Groups of Equal Triangles

The problem asks us to identify groups of equal triangles and write their names. Since there is only one triangle in the figure, there are no groups of equal triangles.

Step 8: Describing the Quadrilateral

The problem mentions the terms "ochotyrykutnyk" (quadrilateral), "opryamokutnyk" (rectangle), and "kvadrat" (square). However, it is not clear how they relate to the figure described in the problem. Could you please provide more information or clarify the connection between these terms and the figure?
