1 Construct angle 3.75° 2 Construct angle 18.75. use any measurements for line AB

3 Construct angle 15° and divide it into 10 equal parts

4 Draw a circle given 3 points A ,b and c

AB = 7.5cm
BC = 7.5cm.

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.
