Question

I am in 10th Std and today my circle exam is there of proofs and theorems that to orally but I dont remember a single thing. it is at 11'o clock. What should I do ? Please answer fast and no spam here or else it will be reported

Answer 1

Answer:

you still have 3 hours just read the therorems and understand their proofs well ...if you have still time left do some very imp ques ...moreover reading theorems will provide you good marks..........all the best

Step-by-step explanation:

Answer 2

Answer:

previous year I also studied tenth standard.

and I too faced  the same problem last year.

In that situation I asked my friend she explained me with the simple words and my mother tongue language.

okay I will help you...

Step-by-step explanation:

• Theorems
• Tangent perpendicular to the radius at the point of contact
• Theorem: The theorem states that “the tangent to the circle at any point is the perpendicular to the radius of the circle that passes through the point of contact”.

(refer image 1)

The number of tangents drawn from a given point

i) If the point is in an interior region of the circle, any line through that point will be a secant. So, no tangent can be drawn to a circle which passes through a point that lies inside it.

AB is a secant drawn

through the point S

ii) When a point of tangency lies on the circle, there is exactly one tangent to a circle that passes through it. (REFER IMAGE 2)

iii) When the point lies outside of the circle, there are accurately two tangents to a circle through it

(REFER IMAGE 3)

Length of a tangent

The length of the tangent from the point (Say P) to the circle is defined as the segment of the tangent from the external point P to the point of tangency I with the circle. In this case, PI is the tangent length.

Lengths of tangents drawn from an external point

Theorem: Two tangents are of equal length when the tangent is drawn from an external point to a circle.
