angles:

(a) 90°​

Answer 1

Answer: Here,

Hey mate,

Step-by-step explanation:

Constructing a 90º Angle:

We can construct a 90º angle either by bisecting a straight angle or using the following steps.  

• Step 1:  Draw the arm PA.
• Step 2:  Place the point of the compass at P and draw an arc that cuts the arm at Q.
• Step 3:  Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R.
• Step 4:  With the point of the compass at R, draw an arc of radius PQ to cut the arc drawn in Step 2 at S.
• Step 5:  With the point of the compass still at R, draw another arc of radius PQ near T as shown.
• Step 6:  With the point of the compass at S, draw an arc of radius PQ to cut the arc drawn in step 5 at T.
• Step 7:  Join T to P. The angle APT is 90º.

For construction please refer to the attachment given.

Good day,

Thanks:)
