Question

Draw triangle ABC with AB =6cm and LA=45°L B =45° and draw its circumcircle?
Measure its circum radius
​

Answer 1

<A = 45° , <B =45°

A+B+C = 180°

45+45+c =180

C = 180-90 =90°

triangle ABC is a right angle triangle

hypotenuse will be diameter of the circle

so circumcenter is midpoint of hypotenuse

circumradius = 1/2* hypotenuse = 0.5*6 = 3cm

hope this is helpful

pls. mark me as brainliest
