Answer:
Therefore the third option is the name of radius i.e
Step-by-step explanation:
Given:
Circle A i.e A is the center of a Circle.
Radius :
The radius of a circle is the distance from the center of the circle to any point on its circumference.
A is the center of a Circle.
Therefore,
Distance From A to B i.e AB =Radius
Distance From A to C i.e AC =Radius
Distance From A to D i.e AD =Radius
Therefore the third option is the name of radius i.e
Also,
Since LM = AM, point M must be on the perpendicular bisector of AL. Since AM = BM, BL must be perpendicular to AL. This makes ∆ALC a right triangle with hypotenuse AC twice the length of side AL. Hence ∠LAC = ∠LAB = 60°, and AL is angle bisector, median, and altitude.
ΔABC is isosceles with ∠A = 120°, and ∠B = ∠C = 30°.
