الهندسة والقياس: إنشاء زاوية متطابقة مع زاوية معلومة

The video tutorial teaches how to duplicate a given angle using geometric tools. It begins with drawing an initial angle and then proceeds to create a second angle that matches the first. The process involves using a compass to draw arcs and measure distances, ensuring the angles are identical. The tutorial concludes with verifying the duplication by drawing a final ray through a specific point.

What is the first step in constructing a congruent angle?

• Identify the vertex of the known angle

• Draw a circle

• Draw a random line

• Use a ruler to measure the angle

Which tool is essential for drawing arcs when constructing a congruent angle?

• Compass

• Set square

• Protractor

• Ruler

What is the purpose of drawing the first arc in the construction process?

• To intersect the rays of the known angle

• To mark the vertex

• To draw a circle

• To measure the angle

After measuring the arc length from the known angle, where should the compass be placed next?

• At the vertex of the known angle

• At the midpoint of the known angle

• At the intersection of the first arc and the new ray

• At the starting point of the new ray

What is the final step in constructing a congruent angle?

• Drawing a circle

• Measuring the angle with a protractor

• Erasing the construction lines

• Drawing the ray through the intersection point
