Question

how to construct an angle of 75 degree​

Answer 1

Answer:

A bisector angle is produced in between 90 degree angle,which gives an angle of 75 degree. The following steps are carried out to construct 75 degree-angle.

Step 1: Draw a ray with end point A and B.

Step 2: With A as center and any radius, draw an arc cutting the ray at point C using a compass.

Step 3: With C as center and the same radius, draw an arc cutting the arc drawn at D.

Step 4: With D as center and the same radius, draw  an arc again intersecting the previously drawn arc at E.

Step 5: Now, take any radius and draw two arcs with D and E as centers. Step 6: Join AF ∠FAB obtained is the angle of measure of 90 degree.

Step 7:The line AF intersect the arc at the point named as G.  

Step 8: With G and D as center draw an arc with radius more than half of the measurement (GD).The arc intersect at the point P.

Step 9: Join the point P and A.∠PAB obtained is the angle of measurement 75 degree.

Answer 2

take your protractor and scale .

now draw a line of any cm and place the protractor on the and the left end of the place the centre point of protractor and Mark the degree 75 and place a dot then, join the dot and the left end of the line
