Question

ПОМОГИТЕ ПОЖАЛУЙСТА срочно. Измерьте и начертите при помощи транспортира с точностью до 1 градуса углы треугольников.Проверьте для каждого треугольник а равна ли сумма углов 180 градусов.

Answer 1

У меня получился треугольник со сторонами a=3; b=4; c=5;
Найдем периметр треугольника:
P=a+b+c;
P=3+4+5=12 см;
Сумма углов треугольника будет всегда равна 180 градусов...

Answer 2

Measuring and Drawing Triangles with a Protractor

To measure and draw the angles of a triangle with a protractor, follow these steps:

1. Measuring the Angles: - Place the protractor on each vertex of the triangle, ensuring that the vertex is at the center of the protractor. - Align one side of the angle with the base line of the protractor. - Read the measurement where the other side of the angle intersects the protractor scale.

2. Drawing the Angles: - Use the measurements obtained to draw the angles accurately with a ruler and pencil.

3. Verifying the Sum of Angles: - After measuring and drawing the angles, verify if the sum of the angles for each triangle equals 180 degrees.

Let's proceed with measuring and drawing the angles for each triangle and then verify if the sum of the angles equals 180 degrees.

I'll start by measuring and drawing the angles for the first triangle.
