To construct an isosceles when altitude CD to the base AB is 2 cm and the vertical angle C = 90o |
| |
 |
| |
 |
| |
(1) Take any straight line XY and at any point D on it, draw cutting off DC = 2 cm. Join DC. |
| |
(2) At C, on either side of DC, construct angles DCA and DCB, respectively, each being equal to 45o, DC bisects  |
| |
| (3) Here, points A and B are the points of intersection of the two arms of the angle with the line XY. |
| |
| (4) \ D ABC is the required isosceles triangle. |
