Construct the following angles using ruler and compass and verify by measuring them by a protractor.

135o


Step of construction:


Step 1: Draw a ray OA.



Step 2: With its initial point O as center and any radius, draw an arc, cutting OA at C.



Step 3: With center c and same radius (as in step 2) draw an arc cutting arc at D.



Step 4: With D as center and the same radius, draw an arc cutting the arc cutting at E.



Step 5: With D and E as centers and any convenient radius (more than DE). Draw to two arcs intersecting at P.



Step 6: Join OP. Then AOP = 90°



Step 7: Bisect AOP towards 180°
