What are the steps in construction class 10?
Steps of Construction:
- Draw a circle with centre O.
- Join the centre O to the given external point P.
- Draw a right bisector of OP to intersect OP at Q.
- Taking Q as the centre and OQ = PQ as radius, draw a circle to intersect the given circle at T and T’.
- Join PT and PT’ to get the required tangents as PT and PT’.
What are the steps in construction class 9?
Steps of Construction :
- Draw a line segment, say XY equal to BC + CA -FAB.
- Make angles LXY equal to ∠B and MYX equal to∠C.
- Bisect ∠LXY and ∠MYX. Let these bisectors intersect at a point A . (
- Draw perpendicular bisectors PQ of AX and RS of AY.
- Let PQ intersect XY at B and RS intersect XY at C. Join AB and AC. (
Do tenth marks matter?
Yes, on the day the result is declared, it matters. Later if you’re applying for competitive exams, your Xth marks need to be above a certain level. Unfortunately, IIMs also allocate some weight to Xth marks.

What are the steps in constructing construction?
Step of construction:
- Draw a circle by taking O as a centre and OA=3 cm (radius)
- Extend OA to B s.t. OA=AB=3 cm.
- Taking A as the centre draw a circle of radius AO=AB=3 cm. Suppose it cuts circle drawn in step 1 at P and Q.
- Join BP and BQ to get the desired tangetns.
