Using a protractor and a ruler draw triangle ABC with A=35°,AC=6cm and C=65°
Start by drawing a 6cm line AC. Use the protractor to create a line from A with an angle of 35. Then use the protractor to draw line CB 65 degrees from C. How many degrees in a triangle? What should angle B be?
I hope this helps.

To draw triangle ABC with angle A measuring 35°, angle C measuring 65°, and side AC measuring 6 cm, you can follow these steps using a protractor and a ruler:
1. Start by drawing a straight line with your ruler. This will be the base line for your triangle, and represent side AB.
2. Mark a point anywhere on the base line. This will be point B, one of the vertices of the triangle.
3. Using your protractor, measure an angle of 35° from point B. Place the protractor on the line, aligning the center hole with point B and the baseline with the protractor's edge. Mark a point where the 35° line intersects the baseline. This will be point A, another vertex of the triangle.
4. Now, measure an angle of 65° from point A. Place the protractor on the line, aligning the center hole with point A and the baseline with the protractor's edge. Mark a point where the 65° line intersects the line segment AB. This will be point C, the remaining vertex of the triangle.
5. Measure 6 cm with your ruler starting from point A and mark a point on the line segment AC. Label this point D.
6. Finally, draw a straight line connecting point C and point D. This will close the triangle.
You have now successfully drawn triangle ABC with A measuring 35°, AC measuring 6 cm, and C measuring 65°.
