Question

construct triangle DEF such that DE=EF=6cm angle F =45 degree ant construct in cirumcircle​

Answer 1

Answer

(i) Draw a line EF=6 cm.

(ii) With F as centre , draw an angle of 45

∘

using the protractor

(iii) With E as centre and 6 cm as radius , cut an arc on ray FX and name its as D

(iv)Join DE. △DEF is thus obtained

(v)Draw the perpendicular bisectors of the lines DF and EF Let these perpendicular bisector meet at point O

(vi)With O as centre and OE as radius , construct a circle touching all the vertices of the △DEF

This circle is thus required circumcircle
