Question

construct triangle ABC with BC =4cm,angleB =90, AB+BC=8cm​

Answer 1

Answer:

Steps of construction:

(1) Draw a line segment XY.

(2) Locate B, C on XY such that BC=4cm

(3)Construct a line segment BD, sufficiently large, such that ∠B=90°

(4)With C as centre and radius 5cm draw an arc, cutting BD at A; join AC.

Then, ABC is the required triangle.
