The correct answer for the first question is C. Set square. A set square, also known as a triangle, is a tool used for constructing angles and bisecting lines. It typically has a right angle and one or more other angles, which can be used to draw various angles and lines.The correct answer for the second question is C. 14 cm. The diameter of a circle is twice its radius. Since the radius of the circle is given as 7 cm, the diameter would be 2 * 7 cm = 14 cm.
