Question

Step-by-step explanation:
Step 1: Draw a line segment with endpoint O and A.
Step 2: Draw an arc with O as centre cutting the line segment OA at point B with a compass.
Step 3: Keeping the radius same, Draw an arc with B as centre cutting the arc at C.
Step 4: Keeping the radius same, and C as the center, draw an arc intersecting the arc drawn in the previous step at D.
Step 5: With any radius, Draw two arcs with C and D as a center. Intersect these two arcs at E.
Step 6: Join OE. angle EOA is the angle with measurement of 90 degrees.
Step 7: Now the line OE intersect the arc at the point F.
Step 8: Taking F and C as a center, make an arc with a radius of more than half of the measurement FC. The arc intersects at point H.
Step 9: Join the point H and O. Angle HOA is the angle obtained of measurement 75 degrees.
Step 10: Angle HOA is the desired angle.​

Answer 1

Answer:

Step 1: Draw a line segment with endpoint O and A.

Step 2: Draw an arc with O as centre cutting the line segment OA at point B with a compass.

Step 3: Keeping the radius same, Draw an arc with B as centre cutting the arc at C.

Step 4: Keeping the radius same, and C as the center, draw an arc intersecting the arc drawn in the previous step at D.

Step 5: With any radius, Draw two arcs with C and D as a center. Intersect these two arcs at E.

Step 6: Join OE. angle EOA is the angle with measurement of 90 degrees.

Step 7: Now the line OE intersect the arc at the point F.

Step 8: Taking F and C as a center, make an arc with a radius of more than half of the measurement FC. The arc intersects at point H.

Step 9: Join the point H and O. Angle HOA is the angle obtained of measurement 75 degrees.

Step 10: Angle HOA is the desired angle.

Answer 2

Answer:

1) Draw a line segment OA.

2) With O as center and a short radius, draw an arc that cuts OA at B.

3) With B as center and the same radius (as in step 2), draw an arc that cuts the first arc at C.

4) With C as center and the same radius (as in step 2), draw an arc that cuts the first arc at D.

5) With C and D as centers, draw two arcs with equal radii such that they intersect at E.

6) Join O and E.

The steps given above are the steps to construct

90∘.

So, ∠AOE=90
