Theory Questions (40 Marks)

1. Using a ruler and compass only, construct a triangle ABC where AB = 7 cm, BC = 6 cm, and AC = 5 cm. Measure the angles of the triangle.

2. Draw a quadrilateral PQRS with PQ = 6 cm, QR = 5 cm, RS = 4 cm, and PS = 7 cm. Construct its diagonals and measure the angles formed at the intersection.

3. Using a ruler and compass, construct an angle of 60° and then bisect it.

4. Define the following terms:
   a) Angle bisector
   b) Perpendicular bisector
   c) Circumference of a circle
   d) Chord

5. A circle has a radius of 7 cm. Calculate the:
   a) Diameter
   b) Circumference
   c) Area of the circle (Use π = 3.142)
