Question

IN ABOVE figure ,
AB is diameter show that angle ACB is a right angle .
Fill the blanks
AB is ______________ given
Arc AXB is __________
m(arc)=____________
measure of semi circle

m angle ACB= 1\2 × _______
=____________
m angle ACB is Right angle​

Answer 1

Answer:

AB is diameter

Arc AXB is 90°

Answer 2

$\huge \fbox \red{❥ Answer}$

AB is 180° given. ( Reason:- It is Straight Line ).

Arc AXB is Minor Arc.

m(arc AXB) = 90° measure of semi circle.

m angle ACB= 1\2 × angle AOB.

Because,

Angle ACB = 90°

ACB = ½AOB

AOB = 45°

If,

Line AB = 180°

Semicircle = ½AB

So,

½ of 180° = 90°
