Question

This is the second part of my homework
pls help me if u can :)

Answer 1

no 4. radius is x

no 5. radius is a

no 6. radius is y

Explanation:

have no idea about tangents

Answer 2

Solution 4 :-

⠀

• Tangent = RY
• Point of tangency = R
• Radius = XT

⠀

Solution 5 :-

⠀

• Radius = TD or DA
• Inscribed Angle = ∠RQS
• Diameter = AT

⠀

Solution 6 :-

⠀

• Radius = YS
• Secant = TU
• Tangent = ST

⠀

★ Important terms to keep in mind :-

⠀

✰ Tangent : Tangent is a line segment which touches the circle, exactly at one point. It is perpendicular to the radius.

⠀

✰ Point of tangency : The point where the tangent and the circle meet, is known as point of tangency.

⠀

✰ Radius : The line segment joining the centre and the end point of the circle is known as radius. It is half the value of diameter of the same circle.

⠀

✰ Diameter : The line segment joining the end points of a circle is known as diameter. It is double the radius.

⠀

✰ Inscribed angle : The angle made by two chords in the interior of the circle, touching any point of the circle is known as inscribed angle.

⠀

✰ Secant : A line segment joining exactly two points of a circle is known as secant.

⠀

✰ Note : If you're acquainted with these terms, you'd be able to tackle such questions easily.
