Construct ∆XYZ such that XY = 3.5 cm, ∠Y = 55˚, YZ = 5 cm. Draw incircle of ∆XYZ.

Answer»

Answer:

Hope it will be helpfull to you

Step-by-step explanation:

(i) Draw a line SEGMENT which is sufficiently long using RULER.

(ii) LOCATE points X and Y on it such that XY=3.5cm.

(iii) At Y, construct a line segment YW, sufficiently large, such that ∠XYZ=100˚ ; use protractor to measure 100˚

(iv) With Y as centre and radius 5.5 CM, draw the line cutting YW at Z; join XZ.

⇒ Then XYZ is the required triangle.
