Question

15 degree by scale and compass​

Answer 1

Bisect 30° to get 15° angle

Step-by-step explanation:

An acute angle is an angle that is more than 0° but less than 90°. Common examples of acute angles include: 15°, 30°, 45°, 60°, etc.

To construct 15^0 angle follow these steps:

Draw a ray L of any length.

Taking centre as O draw an arc with any radius to cut the line L.

Label the intersecting point of L and the arc as B.

Taking centre as B draw an arc with the same radius taken before to cut the previous arc at C.

Join O and C and \angle COA=60^0

Draw an angle bisector OD to the \angle COA and \angle DOB=30^0

Draw an angle bisector OE to the \angle DOB and \angle EOB=15^0 is our required angle
