Drawing 1: Regular pentagon Draw here: (if space is not enough, use another she with side length of 2 cm. Step 1: Start with a circle with a radius of 2 cm. To do this, draw a line segment 2cm long, then use a compass to draw the circle using the segment as the radius. Step 2: Divide the circle into five equal parts by marking points every 72° around the center. Use protractor in doing this. Step 3: Connect the points on the circle formed in step 2 to form the regular pentagon.
Answer (1)
Answer:3. Constructing triangle BCY: We are given BC = 20 cm, ∠B = 95°, and ∠Y = 55°. Note that the sum of angles in a triangle is 180°. Therefore, ∠C = 180° - 95° - 55° = 30°. - Steps:1. Draw a line segment BC of length 20 cm.2. At point B, construct an angle of 95° using a protractor.3. At point C, construct an angle of 30° using a protractor.4. The intersection of the rays from B and C is point Y, completing triangle BCY.
